These rwo conditional compile symbols are explicitely defined.
As a result, their included code is always compiled. They could be
converted to Kconfig symbols; however, my experience with this driver
in a GitHub repo is that many users of the device have it built into
a SOC or SBC that they wish to use as an access point. As a result,
CONFIG_88EU_APMODE would need to be selected. Thuse it should be built in.

There have also been many users the wish to establish peer-to-peer
networks with this device. For this reason, I am also proposing that
CONFIG_88EU_P2P be automatically included.

Remove _enter_critical_mutex() and _exit_critical_mutex(). They are
unnecessary wrappers, respectively to mutex_lock_interruptible() and
to mutex_unlock(). They also have an odd interface that takes an unused
argument named pirqL of type unsigned long.
The original code enters the critical section if the mutex API is
interrupted while waiting to acquire the lock; therefore it could lead
to a race condition. Use mutex_lock() because it is uninterruptible and

[  252.065168] but task is already holding lock:
[  252.065536] ffffffffc021b3b8 (pmutex){+.+.}-{4:4}, at:  netdev_open+0x3a/0x5f [r8188eu]
[  252.066085]
[  252.066085] other info that might help us debug this:
[  252.066494]  Possible unsafe locking scenario:
[  252.066494]
[  252.066866]        CPU0
[  252.067025]        ----
[  252.067184]   lock(pmutex);
[  252.067367]   lock(pmutex);

There is one problem with this warning: there is no pmutex in this
driver, *BUT* all mutexes are initialized via private _rtw_mutex_init
API, which had struct mutex *pmutex argument.

So, all mutexes in this driver had same name in lockdep map. Of course,
lockdep will complain about any nested locking.

Fix it by open-coding _rtw_mutex_{init,free} wrappers, because we do not
need them at all.

staging: r8188eu: remove useless check

smatch says:
usb_intf.c:326 rtw_hw_suspend() warn: variable dereferenced before check 'padapter' (see line 323)
usb_intf.c:387 rtw_hw_resume() warn: variable dereferenced before check 'padapter' (see line 385)

There is only one caller of rtw_hw_suspend() and it does not check
padapter pointer, so let's just omit this check to make smatch happy.

staging: r8188eu: remove rtw_hal_c2h_id_filter_ccx function

Remove rtw_hal_c2h_id_filter_ccx from hal/hal_intf.c and its one caller
from core/rtw_cmd.c. This function is a wrapper function which returns
the c2h_id_filter_ccx function pointer of struct hal_ops unconditionally.
As this function pointer is never set, and the function call's return
value is subsequently called inside an if condition, this could lead to
an attempt to deference a NULL pointer, which would crash the driver.
