xfree86/modes: Assign xf86_config->cursor in xf86_load_cursor_image v2

Browse Source 
Fixes a crash on startup in the radeon driver's drmmode_show_cursor()
due to xf86_config->cursor == NULL, because no CRTC was enabled yet, so
xf86_crtc_load_cursor_image was never called.

(Also use scrn->pScreen instead of xf86ScrnToScreen(scrn))

v2: Set xf86_config->cursor at the beginning of xf86_load_cursor_image
    instead of at the end.
