[PATCH v2 0/2] Improve ufence addr validation and error handling

[Nirmoy Das <nirmoy.das@intel.com>]

Resending https://patchwork.freedesktop.org/series/139887/ with 
Test-with tag to validate we catch bogus addr from userspace early.

Locally I can reproduce current bogus addr passing issue and the test
also validate that it is fixed with the 1st patch.

v2: s/XE_WARN_ON/drm_dbg(Maarten)
