Set the request queue of a TYPE_ZBC device as needing zone append emulation by setting the device queue max_zone_append_sectors limit to 0. This enables the block layer generic implementation provided by zone write plugging. With this, the sd driver will never see a REQ_OP_ZONE_APPEND request and the zone append emulation code implemented in sd_zbc.c can be removed.
