raspberry: Fixed missing mouse cursor (thanks, Joe!) 

"Starting with changeset 12433, the mouse cursor is not displayed on the
Raspberry Pi platform, due to a bug in the handling of the new
"global_cursor" in RPI_ShowCursor(). Currently, if cursor == global_cursor,
the function immediately returns 0. The function should not return here.
Instead, if cursor == global_cursor, it shouldn't try to hide the current
cursor and update global_cursor = cursor. However, it *should* still continue
through the rest of the function."

Fixes Bugzilla #4699.
