btrfs: validate queue limits

Call blk_validate_limits on the queue limits used for zone append
splitting so that calculated values get filled in and any stacking
conflicts get cought.

Without this there isn't a max_zone_append_sectors limits as of commit
559218d43ec9 ("block: pre-calculate max_zone_append_sectors").
