[PATCH weston] Copying xkb_info when creating a seat causes problems

[Andrew Wedgbury]

A simpler fix would be to not call xkb_info_destroy() when releasing a seat in the case where the xkb_info for the seat was copied from the global compositor settings (which can be determined by checking if keymap_fd is the same)

In this case, xkb_map_unref() should still be called to unref the keymap.

This appears to fix things for me, so I can now create and destroy many seats.
