rxrpc: Downgrade the BUG() for unsupported token type in rxrpc_read()
[ Upstream commit 9a059cd5ca7d9c5c4ca5a6e755cf72f230176b6a ]
If rxrpc_read() (which allows KEYCTL_READ to read a key), sees a token of a
type it doesn't recognise, it can BUG in a couple of places, which is
unnecessary as it can easily get back to userspace.
Fix this to print an error message instead.
Fixes: 99455153d067 ("RxRPC: Parse security index 5 keys (Kerberos 5)")
