[PATCH xserver] xfree86/common: Fix VT leave lockup #103782

[Алексей Шилин]

When xf86VTSwitchAway() returns true to xf86VTLeave(), the input
mutex does not get unlocked. As the result, any other thread which
later tries to execute input_lock() freezes forever, which in turn
may lead to X server lockup.

This commit adds the missing input_unlock() call.
