[PATCH] null_blk: Fix zoned command return code

[kbusch@kernel.org]

From: Keith Busch <kbusch@kernel.org>

The return code from null_handle_zoned() sets the cmd->error value. Returning
OK status when an error occured overwrites the intended cmd->error. Return the
appropriate error code instead of setting the error in the cmd.

Fixes: fceb5d1b19cbe626 ("null_blk: create a helper for zoned devices")
