From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently there is a while loop that contains a handful of continue
statements that can skip over the assignment of the variable err. At
the end of the loop there is a potiential for err to be unassigned
and possibly causing issues when err is checked for a non-zero value.
Fix this by setting err to zero before the while loop starts.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: cf41a8f1dc1e ("drm/i915: Finally remove obj->mm.lock.")
