null_blk: replace null_process_cmd() call in null_zone_write()

Browse source

As a preparation to support partial data transfer due to badblocks,
replace the null_process_cmd() call in null_zone_write() with equivalent
calls to null_handle_badblocks() and null_handle_memory_backed(). This
commit does not change behavior. It will enable null_handle_badblocks()
to return the size of partial data transfer in the following commit,
allowing null_zone_write() to move write pointers appropriately.
