ceph: eliminate session->s_trim_caps
It's only used to keep count of caps being trimmed, but that requires that we hold the session->s_mutex to prevent multiple trimming operations from running concurrently. We can achieve the same effect using an integer on the stack, which allows us to (eventually) not need the s_mutex.
