Subject: [PATCH 06/28] staging/lustre/osc: Fix reverted condition in osc_lock_weight

When importing clio simplification patch, the check for
object got reversed by mistake when converting from
if (obj == NULL) it somehow became if (obj) which is obviously wrong,
and so when it does hit, a crash was happening as result.

Fix the condition and all if fine now.
