crypto: qat/adf_aer - Replace GFP_ATOMIC with GFP_KERNEL in adf_dev_aer_schedule_reset() 

adf_dev_aer_schedule_reset() is never called in atomic context, as it
calls wait_for_completion_timeout().

adf_dev_aer_schedule_reset() calls kzalloc() with GFP_ATOMIC,
which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

This is found by a static analysis tool named DCNS written by myself.
I also manually check the kernel code before reporting it.
