nvme-multipath: set BLK_FEAT_ZONED only after the zone info is known
The namespace head is marked zoned at allocation time based only on the
command set identifier. If the zone info query reports a zero zone size,
the path namespace is registered without zoned limits while the head
still advertises the zoned capability with a zone size of zero, and
reporting zones or writing to the head then shifts by ilog2(0).
Drop the zoned feature from the head allocation and let the head limits
refresh stack it in from the path namespace instead.
