greybus: connection: Fix sparse warnings around locking

Browse source

The callers ensures that connection->lock is taken before calling few
routines, but that isn't enough for sparse as it sees an unexpected
unlock.

greybus/connection.c:380:29: warning: context imbalance in 'gb_connection_cancel_operations' - unexpected unlock

Fix that adding __must_lock() attribute to the function declaration.

This also adds the attribute for
gb_connection_flush_incoming_operations(), which isn't showing any
sparse warnings with the current state of code, but with minor
rearrangements of the code.
