[PATCH] winedbg: rex is not used for Grp15b (Coverity)

[Marcus Meissner]

Coverity complained about a static overrun when rex is set,
Discussed with Eric, for Grp15b "rex" is not evaluated,
so suppresss its  usage.

The same might be true for other db_Grp calls, but its quite
hard to review, so fix this one first.

Ciao, Marcus
