powerpc: Don't allow the use of EMIT_BUG_ENTRY with BUGFLAG_WARNING
Warnings in assembly must use EMIT_WARN_ENTRY in order to generate the necessary entry in exception table. Check in EMIT_BUG_ENTRY that flags don't include BUGFLAG_WARNING. This change avoids problems like the one fixed by commit fd1eaaaa ("powerpc/64s: Use EMIT_WARN_ENTRY for SRR debug warnings").
