net: mctp: hold key reference when looking up a general key
Currently, we have a race where we look up a sock through a "general"
(ie, not directly associated with the (src,dest,tag) tuple) key, then
drop the key reference while still holding the key's sock.
This change expands the key reference until we've finished using the
sock, and hence the sock reference too.
