PM: hibernate: fix sparse warnings
When building the kernel with sparse enabled 'C=1' the following
warnings shows up:
kernel/power/swap.c:390:29: warning: incorrect type in assignment (different base types)
kernel/power/swap.c:390:29: expected int ret
kernel/power/swap.c:390:29: got restricted blk_status_t
This is due to function hib_wait_io() returns a 'blk_status_t' which is
a bitwise u8. Commit 5416da01ff6e ("PM: hibernate: Remove
blk_status_to_errno in hib_wait_io") seemed to have mixed up the return
type. However, the 4e4cbee93d56 ("block: switch bios to blk_status_t")
actually broke the behaviour by returning the wrong type.
Rework so function hib_wait_io() returns a 'int' instead of
'blk_status_t' and make sure to call function
blk_status_to_errno(hb->error)' when returning from function
hib_wait_io() a int gets returned.
Fixes: 4e4cbee93d56 ("block: switch bios to blk_status_t")
Fixes: 5416da01ff6e ("PM: hibernate: Remove blk_status_to_errno in hib_wait_io")
