Dan Carpenter 5e4cf2bf6d tracing: Fix a potential NULL dereference ...

We forgot to set the error code on this path so we return ERR_PTR(0)
which is NULL.  It results in a NULL dereference in the caller.

Link: http://lkml.kernel.org/r/20180323113735.GC28518@mwanda

Fixes: 100719dcef ("tracing: Add simple expression support to hist triggers")
