drm/msm: Reduce fallout of fence signaling vs reclaim hangs

Browse Source 
[ Upstream commit 4bea53b9c7 ]

Until various PM devfreq/QoS and interconnect patches land, we could
potentially trigger reclaim from gpu scheduler thread, and under enough
memory pressure that could trigger a sort of deadlock.  Eventually the
wait will timeout and we'll move on to consider other GEM objects.  But
given that there is still a potential for deadlock/stalling, we should
reduce the timeout to contain the damage.
