meta: Silence unused parameter warning in _mesa_meta_CopyTexSubImage

drivers/common/meta.c: In function '_mesa_meta_CopyTexSubImage':
drivers/common/meta.c:3744:52: warning: unused parameter 'rb' [-Wunused-parameter]

Unfortunately, the parameter can't just be removed because it is part of
the dd_function_table::CopyTexSubImage interface.
