drm: Fix GETCONNECTOR regressiondrm-misc-fixes-2017-06-22

commit 91eefc05f0ac71902906b2058360e61bd25137fe

drm: Tighten locking in drm_mode_getconnector
I reordered the logic a bit in that IOCTL, but that broke userspace
since it'll get the new mode list, but not the new property values.
Fix that again.
v2: Fix up the error path handling when copy_to_user for the modes
failes (Dhinakaran).
