mtip32xx: add error handling support for add_disk()
We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. The read_capacity_error error label already does what we need, so just re-use that. Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
