[PATCH 4.15 087/146] x86/LDT: Avoid warning in 32-bit builds with older gcc

4.15-stable review patch.  If anyone has any objections, please let me know.


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.
