greybus: legacy: fix a null pointer dereference

Browse source

When gb_protocol_get() fails in legacy_connection_create(), we end up
bailing-out before assigning lc->connection and lc->protocol. Calling
legacy_connection_destroy() in that case results in a null pointer
dereference.

Check if lc->connection is not null before freeing it.
