xfree86/modes: Check for CRTC transforms in xf86_use_hw_cursor(_argb) (v2)

Browse Source 
We currently don't handle transforms for the HW cursor image, so return
FALSE to signal a software cursor must be used if a transform is in use
on any CRTC.

v2: Check crtc->transformPresent instead of crtc->transform_in_use. The
    latter is TRUE for rotation as well, which we handle correctly.
