Subject: [PATCH 09/32] fix(dracut-functions.sh): only return block devices
 from get_persistent_dev

With udev 256, there are now directories such as
/dev/disk/by-path/pci-0000:02:00.0-nvme-1-part/ which match here.

In case a nonexisting file/device was passed to get_persistent_dev, it
returned the first directory it looked at because both have maj:min 0:0.
This accidental conversion from garbage to a sensible looking path leads
to weird behaviour later.

Instead of filtering out directories explicitly switch the check to only
return block devices, which also takes care of the character special
/dev/mapper/control.

(cherry picked from commit 55d2fb5b459f356fdbde60ddefb97be942a0c141)

Resolves: RHEL-49744
