Handle errno properly to avoid corrupt str_parms

A normal sequence of calls is as follows:
str_parms_create_str, str_parms_add_str, str_parms_destroy.
In some cases the destroy caused double free.

str_parms_add_str will clone the input and send it to hashmapPut
for storage. If hashmapPut did not store the strings it will raise
errno = ENOMEM and leave caller with ownership of the strings.
In any of these cases it will be safe to destroy the str_parms.

But what if it wasn't hashmapPut that said NOMEM? What if there
was a stale NOMEM already before a successful hashmapPut?
In that case the strings will be successfully added to the list
(if new), but when str_parms_add_str sees the NOMEM it will free
them anyway, leaving dangling pointers in the str_parms!!

It is the responsibility of the caller to clear errno before any
interesting call. This patch makes sure that str_parms_add_str
reacts only on errno emmitted from hashmapPut.
