Subject[RFC PATCH v1 3/4] ubifs: auth: remove never hit key type error check
Date
key_request accepts a key type as its first argument. If it returns a
valid pointer, it should always have this same requested key type.

Indeed other request_key users surveyed such as dm-crypt, ecryptfs
and fscrypt v1 also don't check the key type. Therefore drop the
apparently unneeded check.
