Christophe Leroy 38a1756861 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 fd1eaaaaa686 ("powerpc/64s: Use EMIT_WARN_ENTRY for SRR debug
warnings").
