scsi: scsi_debug: Map the region written by WRITE ATOMIC (16)

When logical block provisioning is enabled, every command that writes user
data calls map_region() so that GET LBA STATUS reports the region as
mapped. resp_atomic_write() does not, so GET LBA STATUS keeps reporting a
region as deallocated after a WRITE ATOMIC (16) has written it.

Call map_region() the way resp_write_dt0() does, holding the zone metadata
write lock across the access. That lock is what serialises the map against
resp_unmap(), which does nothing unless logical block provisioning is
enabled.
