drm_hwcomposer: check if the primary plane is being used by any crtc
Some DRM driver such as omap_drm allow sharing primary plane between CRTCs.
drm_hwcomposer isn't ready for such a scenarios and fails with an error:
Found more than 1 primary plane for CRTC
Don't report multiple primary planes for single CRTC to satisfy the drm_hwc.
