Error handling in md_alloc is a mess. Untangle it to just free the mddev
directly before add_disk is called and thus the gendisk is globally
visible. After that clear the hold flag and let the mddev_put take care
of cleaning up the mddev through the usual mechanisms.
Fixes: 5e55e2f5fc95 ("[PATCH] md: convert compile time warnings into runtime warnings")
Fixes: 9be68dd7ac0e ("md: add error handling support for add_disk()")
Fixes: 7ad1069166c0 ("md: properly unwind when failing to add the kobject in md_alloc")
