We were only storing the FB provided by the client, but on CRTCs with TearFree enabled, we use a separate FB. This could cause drmmode_flip_handler to fail to clear drmmode_crtc->flip_pending, which could result in a hang when waiting for the pending flip to complete. We were trying to avoid that by always clearing drmmode_crtc->flip_pending when TearFree is enabled, but that wasn't reliable, because drmmode_crtc->tear_free can already be FALSE at this point when disabling TearFree. Now that we're keeping track of each CRTC's flip FB separately, drmmode_flip_handler can reliably clear flip_pending, and we no longer need the TearFree hack.
