re PR other/79250 (brig/brigfrontend/brig-to-generic.cc: two small problems)

* brigfrontend/brig-code-entry-handler.cc: fix address
expressions which refer only to offset 0, but nothing else.
* brigfrontend/brig-lane-inst-handler.cc: fix
activelanepermute_b64 HSAIL instruction.
* brigfrontend/brig-to-generic.cc: remove useless c_str()
call. Add missing va_end (). Fix PR79250
