crypto: api - Only abort operations on fatal signal
Currently a number of Crypto API operations may fail when a signal occurs. This causes nasty problems as the caller of those operations are often not in a good position to restart the operation. In fact there is currently no need for those operations to be interrupted by user signals at all. All we need is for them to be killable. This patch replaces the relevant calls of signal_pending with fatal_signal_pending, and wait_for_completion_interruptible with wait_for_completion_killable, respectively.
