In rtw_free_netdev() there are two redundant tests. The first checks for
a valid pointer to a "struct net_device". This pointer is the argument
of rtw_free_netdev(). The two callers of this function already test this
parameter immediatelly before the calls. The second checks for a valid
pointer to a "struct rtw_netdev_priv_indicator". This pointer is always
valid and, even if it were not, vfree() is a no-op on NULL pointers.
Therefore the above-mentioned two "if" statements are unnecessary and
redundant. For this reason, remove these two tests.
After removing these tests there is no more need of the "RETURN" label.
Therefore, remove also the "RETURN" label.

staging: vc04_services: Convert kmap() to kmap_local_page()
The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible. In file interface/vchiq_arm/vchiq_arm.c,
function free_pagelist() calls kmap() / kunmap() from two places.
With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Therefore, free_pagelist() is a function where the
use of kmap_local_page() in place of kmap() is correctly suited.
Convert to kmap_local_page() but, instead of open coding it, use the
memcpy_to_page() helper.

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.
