If symlink (e.g. /dev/md/raid) is passed as a parameter to mdadm --wait,
it fails as it's not able to find a corresponding entry in /proc/mdstat
output. Get parameter file major:minor and look for block device name in
sysfs. This commit is partial revert of commit 9e04ac1c43e6
("mdadm/util: unify stat checking blkdev into function").
