greybus: count rather than list protocol users
We don't really need a list of protocol users, we can just keep
track of how many there are. Get rid of the list and use a count
instead.
Also, have gb_protocol_get() return the protocol rather than assigning
a passed-in connection pointer's protocol. Make a comparable change
to the gb_protocol_put() interface.
Get rid of gb_protocol_find() (the version that locks), because it
is no longer needed.
