Gerd Rausch 3a2886cca7 net/rds: Keep track of and wait for FRWR segments in use upon shutdown
Since "rds_ib_free_frmr" and "rds_ib_free_frmr_list" simply put
the FRMR memory segments on the "drop_list" or "free_list",
and it is the job of "rds_ib_flush_mr_pool" to reap those entries
by ultimately issuing a "IB_WR_LOCAL_INV" work-request,
we need to trigger and then wait for all those memory segments
attached to a particular connection to be fully released before
we can move on to release the QP, CQ, etc.

So we make "rds_ib_conn_path_shutdown" wait for one more
atomic_t called "i_fastreg_inuse_count" that keeps track of how
many FRWR memory segments are out there marked "FRMR_IS_INUSE"
(and also wake_up rds_ib_ring_empty_wait, as they go away).
