various comment / whitespace tweaks (libmsc, gprs, libcommon-cs)

cosmetic ws in common_cs_vty.c, osmo_msc.c

comment: tiny typo fix in gsm_04_08.c

In comments, drop some unbalanced braces, because simplistic C file harvesters
will break at a single opening brace even if it is in a comment. This is aimed
at the fsm-to-dot.py script in libosmocore/contrib.
