sd: remove sd_is_zoned

Browse Source 
Since commit 7437bb73f0 ("block: remove support for the host aware zone
model"), only ZBC devices expose a zoned access model.  sd_is_zoned is
used to check for that and thus return false for host aware devices.

Replace the helper with the simple open coded TYPE_ZBC check to fix this.
