PM: hibernate: Fix writing maj:min to /sys/power/resume
resume_store() first calls lookup_bdev() and after tries to handle
maj:min, but it does not reset the error before, hence if you will write
maj:min you will get ENOENT:
# echo 259:2 >| /sys/power/resume
bash: echo: write error: No such file or directory
This also should fix hiberation via systemd, since it uses this way.
Fixes: 1e8c813b083c4 ("PM: hibernate: don't use early_lookup_bdev in resume_store")
