PM: hibernate: Drop NULL pointer checks before acomp_request_free()

Since acomp_request_free() checks its argument against NULL, the NULL
pointer checks before calling it added by commit ("7966cf0ebe32 PM:
hibernate: Fix crash when freeing invalid crypto compressor") are
redundant, so drop them.

No intentional functional impact.
