Bug Description

[Impact]
 * Normal server shutdown will crash when using nvidia in the 319 recommended optimus setup, or when using usb displaylink output.

[Test Case]
 * Start X on an Intel system with a DisplayLink device attached, or nvidia in optimus configuration.
 * xrandr --setprovideroutputsource modesetting NVIDIA-0, or xrandr --setprovideroutputsource modsetting Intel
 *. xrandr --output DVI-0 --off (bug #1185014 workaround)
 * xrandr --auto
 * Shutdown xserver, no crash should happen.

[Regression Potential]
 * Low, the codepath affected only happens on server shutdown, which is already crashing anyway.
 * Considering the code affected, xrandr --setprovideroutputsource and --setprovideroffloadsink will be the most likely candidates if regressions do occur.

[Other Info]
 * Not upstream yet, but expected there soon.
