staging: r8188eu: Add _enter_critical_mutex() error handling
_enter_critical_mutex() is a simple call to mutex_lock_interruptible(),
but there is no error handling code for it.
The patch removes wrapper _enter_critical_mutex() and
adds error handling for mutex_lock_interruptible().
Found by Linux Driver Verification project (linuxtesting.org).
