gpu: nvgpu: disable elpg before ctxsw_disable
if fecs is sent stop_ctxsw method, elpg entry/exit cannot happen
and may timeout. It could manifest as different error signatures
depending on when stop_ctxsw fecs method gets sent with respect
to pmu elpg sequence. It could come as pmu halt or abort or
maybe ext error too.
If ctxsw failed to disable, do not read engine info and just abort tsg.
