drm/xe/ufence: ufence can be signaled right after wait_woken
do_comapre() can return success after a timedout wait_woken() which was
treated as -ETIME. The loop calling wait_woken() sets correct err so
there is no need to re-evaluate err.
v2: Remove entire check that reevaluate err at the end(Matt)
Fixes: e670f0b4ef24 ("drm/xe/uapi: Return correct error code for xe_wait_user_fence_ioctl")
