Yogish Kulkarni df6a3a07f6 Skip SetCursor when vtSema is FALSE.

Consider below sequence -
1) Cursor is removed : isUp will be FALSE if HW cursor is set.
2) VT switched away from X : vtSema becomes FALSE.
3) xf86CursorSetCursor is called with non-null CursorPtr :
Saves the passed in CursorPtr, fallbacks to SW cursor and invokes
spriteFuncs->SetCursor which saves the area under cursor and restores
the cursor. This sets isUp to TRUE and as vtSema is FALSE saved data
is garbage.
4) VT switched to X : vtSema becomes TRUE. xf86Cursor enable fb access
is called which will remove the SW cursor, i.e copies saved data in #3
to screen.

This results to momentary garbage data on screen. Hence when !vtSema
skip spriteFuncs->SetCursor.
