modesetting: Hide cursor when initializing crtc

Browse Source 
When Xorg gets started directly from a wayland-gdm the crtc still has the
wayland hw cursor set. Combine this with Xorg immediately falling back to
a sw cursor because a slave-output has a monitor attached at startup; and
we end up with the wayland hardware cursor overlay fixed in its last
position + the Xorg sw cursor resulting in 2 cursors.

This commit fixes this by hiding any left-over cursors when initializing
the crtc.
