x86: Remove "%!" before ret
Before MPX was removed, "%!" was mapped to
case '!':
if (ix86_bnd_prefixed_insn_p (current_output_insn))
fputs ("bnd ", file);
return;
After CET was added and MPX was removed, "%!" was mapped to
case '!':
if (ix86_notrack_prefixed_insn_p (current_output_insn))
fputs ("notrack ", file);
return;
ix86_notrack_prefixed_insn_p always returns false on ret since the
notrack prefix is only for indirect branches. Remove the unused "%!"
before ret.
