dm: zoned: Remove unused functions
dmz_resume_metadata() is unused since it was added in commit3b1a94c88b
("dm zoned: drive-managed zoned block device target") dmz_zone_nr_blocks_shift is unused since it was added in commit3682056013
("dm zoned: move fields from struct dmz_dev to dmz_metadata") Remove them. Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com>
