btrfs-progs: replace blkid_probe_get_wholedisk_devno
blkid_probe_get_wholedisk_devno() isn't available in some older
versions of libblkid. It was used to work around an old
bug in blkid_devno_to_wholedisk(), but that has been fixed since
5cd0823 libblkid: fix blkid_devno_to_wholedisk(), present in
util-linux 2.17 and beyond.
If we happen to be missing that fix, the worst that happens is
that we'd fail to detect that a device is an ssd; the upside is
that this code compiles on older systems.
