PM: hibernate: Remove blk_status_to_errno in hib_wait_io

fallazc · rafaeljw · commit 5416da01ff6e · 2021-09-15T14:17:14.000+02:00
blk_status_to_errno doesn't appear to perform extra work besides
converting blk_status_t to integer. This patch removes that unnecessary
conversion as the return type of the function is blk_status_t.
