[PATCH 3/9] mspro_block: 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.

Contrary to the typical removal which delays the put_disk()
until later, since we are failing on a probe we immediately
put the disk on failure from add_disk by using
blk_cleanup_disk().
