[libvirt] [PATCH v2 4/6] esx: Resolve Coverity FORWARD_NULL
Coverity complains that strtok_r cannot be called if the first and third
parameters are NULL. On entry, the 'path' parameter is not checked for
being NULL before the VIR_STRDUP which will set the target to NULL if
the source (eg path) is NULL. Thus add a check for NULL path.
NB: Checks were made in the caller to only call this function if that
parameter was non-NULL; however, that didn't satisfy the checker. The
check had to be in this function.
