    drm/i915: Eliminate lots of iterations over the execobjects array

without any motivation.

I suspect it was added to handle EAGAIN errors from userptr, but it's
hard to guess with no breadcrumbs anywhere. Before this change there
wasn't any dedicated EAGAIN handling, we just bounced completely to
userspace.

Userptr works differently now and does not just thrash the cpu until
another worker has maybe acquired the pages, so we can go back to
handling EAGAIN like beforehand.

That also allows us to drop another funky repeat loop from a function
with already very complicated control flow (which unforunately got
more complex due to ww_mutex restarting).
