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.

staging: r8188eu: Remove _enter/_exit_critical_mutex()

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
so avoid that above-mentioned potential race condition.

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.
