drm: Make drm_dp_mst_dsc_aux_for_port() safe for old compilers

Older compilers either want two extra pairs of curly braces around the
initializer for local variable desc, or they want a single pair of curly
braces with nothing inside.  Because current Linux-kernel practice favors
the latter, this commit makes it so.
