Subject: x86/LDT: Avoid warning in 32-bit builds with older gcc

From: Jan Beulich <JBeulich@suse.com>

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.
