Subject: x86/LDT: Avoid warning in 32-bit builds with older gcc
From: Jan Beulich <JBeulich@xxxxxxxx>
commit f2f18b16c779978ece4a04f304a92ff9ac8fbce5 upstream.
BUG() doesn't always imply "no return", and hence should be followed by
a return statement even if that's obviously (to a human) unreachable.
