drm/msm: make sure to not queue up recovery more than once

Browse source

[ Upstream commit 10fb1b2fca ]

If two fault IRQs arrive in short succession recovery work will be
queued up twice.

When recovery runs a second time it may end up killing an unrelated
context.

Prevent this by masking off interrupts when triggering recovery.
