[fedfs-utils] [PATCH 08/12] fedfsd: don't double-free upon ENOMEM

[Chuck Lever]

From: Jim Meyering <meyering at redhat.com>

* src/fedfsd/svc.c (fedfsd_pathwalk): If nsdb_normalize_path were
to return NULL, "result" would be freed once by the very next stmt,
and then again in the following "if"-block.  Remove the latter.
Spotted by coverity.

Introduced by commit 0520ee72: "Initial commit," (March 29, 2011).
