radeon_do_pageflip() indexed the flipdata->fb[] array
indexing over config->num_crtc, but the flip completion
routines, e.g., drmmode_flip_handler(), index that array
via the crtc hw id from drmmode_get_crtc_id(crtc).
This is mismatched and causes indexing into the wrong
array slot at flip completion -> Server crash.
Always use drmmode_get_crtc_id(crtc) for indexing into
the array to fix this.
Tested on a dual-X-Screen setup with one video output
assigned to each X-Screen, page-flipping an OpenGL app
on either of both X-Screens. This used to crash when
flipping on X-Screen 1, now it doesn't anymore.
Fixes: 740f0850f1 "Store FB for each CRTC in drmmode_flipdata_rec"
