Alexey Khoroshilov f19885fadf staging: sep: call to sep_ioctl() may leave driver in unusable state 
If sep_ioctl() is called from a process that does not own
current transaction, it unlocks unheld sep->ioctl_mutex and
returns -EACCES leaving sep->sep_mutex acquired.

The patch fixes the mutex lock-unlock mismatch.

Found by Linux Driver Verification project (linuxtesting.org).
