This patch creates a helper function for handling zoned block device operations. This patch also restructured the code for null_blk_zoned.c and uses the pattern to return blk_status_t and catch the error in the function null_handle_cmd() into cmd->error variable instead of setting it up in the deeper layer just like the way it is done for flush, badblocks and memory backed case in the null_handle_cmd(). We also move null_handle_zoned() to the null_blk_zoned.c to keep the zoned code separate. Signed-off-by:
