IB/sa: Fix sa_local_svc_timeout_ms read race

Browse source

[ Upstream commit 1428cd764c ]

When computing the delta, the sa_local_svc_timeout_ms is read without
ib_nl_request_lock held. Though unlikely in practice, this can cause
a race condition if multiple local service threads are managing the
timeout.
