drm/i915: fix gen4 gpu reset
While trying to fix up gen4 gpu reset in
commit f49f0586191fe16140410db0a46d43bdc690d6af

drm/i915: Actually set the reset bit in i965_reset
a little confusion about when wait_for times out has been introduced -
wait for loops _until_ the condition is true.
This fixes gpu reset on my gm45, testing with my hangman code shows
that it's now fairly reliable - it only died after well over 100 reset
cycles.
