dm: zoned: Remove unused functions

dmz_resume_metadata() is unused since it was added in commit
3b1a94c88b79 ("dm zoned: drive-managed zoned block device target")

dmz_zone_nr_blocks_shift is unused since it was added in commit
368205601375 ("dm zoned: move fields from struct dmz_dev to dmz_metadata")

Remove them.
