drm/nouveau: fix another lock unbalance in nouveau_crtc_page_flip
commit 806cbc5026933a781b66adecf6d1658fde9138e6 upstream.
Fixes a regression introduced by 060810d7abaabca "drm/nouveau: fix locking
issues in page flipping paths". chan->cli->mutex is unlocked a second time
in the fail_unreserve path, fix this by moving mutex_unlock down.
