When a slave-output is rotated the transformation is done on the blit from master to slave GPU, so crtc->transform_in_use is not set, but we still need to adjust the mouse position for things to work. This commit modifies xf86_crtc_transform_cursor_position to not rely on crtc->f_framebuffer_to_crtc, so that it can be used with GPU screens too and always calls it for crtcs with any form of rotation. Note not using crtc->f_framebuffer_to_crtc means that crtc->transform will not be taken into account, that is ok, because when we've a transform active hw-cursors are not used and xf86_crtc_transform_cursor_position will never get called.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
