Subject: path-util: set pointer to null after calling free()
X-Git-Tag: v197~122

path-util: set pointer to null after calling free()

In cases where path_strv_canonicalize() returns NULL, strv_free() is
called afterwards and it will call free() on pointers which were freed
already in path_strv_canonicalize()
