Reference-drop trace in drm_pagemap_dev_unhold_work() was changed
from drm_dbg() to drm_dbg_ratelimited() to reduce serial console
bottlenecks.
However, when the ratelimit kicks in, the kernel's ratelimiting subsystem
logs a "callbacks suppressed" notification at the KERN_WARNING level.
Revert the trace macro back to drm_dbg()

Fixes: b66b036c959f ("drm/pagemap: Prevent CPU stalls during unbounded pagemap teardown")
