btrfs: optimize out btrfs_is_zoned for !CONFIG_BLK_DEV_ZONED

Browse Source 
Add an IS_ENABLED check for CONFIG_BLK_DEV_ZONED in addition to the
run-time check for the zone size.  This will allow to make use of
compiler dead code elimination for code guarded by btrfs_is_zoned, and
for example provide just a dangling prototype for a function instead of
adding a stub.
