crypto: gcm - wait for crypto op not signal safe
crypto_gcm_setkey() was using wait_for_completion_interruptible() to
wait for completion of async crypto op but if a signal occurs it
may return before DMA ops of HW crypto provider finish, thus
corrupting the data buffer that is kfree'ed in this case.
Resolve this by using wait_for_completion() instead.
