[PATCH 1/1] staging: lustre/lustre/obdclass/llog_cat.c: get rid of sparse context imbalance warning

[Tolga Ceylan]

In llog_cat_new_log(), sparse emits a context imbalance (unexpected lock)
warning due its inability to detect the noreturn attribute in
lbug_with_lock() function inside LBUG macro. Adding a never reached
return statement suppresses this warning.
