[PATCH v1] PM: hibernate: Drop NULL pointer checks before acomp_request_free()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

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.
