Problem:
* Memory leak exists in reconfigure function when multipathd command "reconfigure" is executed.
Reasons:
* The following judgement condition is not satisfied when there is no path , free_pathvec is not called to free the vector of vecs->pathvec:
if (VECTOR_SIZE(vecs->pathvec))
free_pathvec(vecs->pathvec, FREE_PATHS);
* Then the vecs->pathvec is set to NULL, so the vector memory which vecs->pathvec pointed to is leaked:
vecs->pathvec = NULL;
