rxrpc: Downgrade the BUG() for unsupported token type in rxrpc_read()

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: 35cef4351aa0 ("RxRPC: Parse security index 5 keys (Kerberos 5)")
