Title: #679: UTIL: Suppress Coverity warning
We recently added this code:
if (domain_name != NULL
find_domain_by_name returns NULL if the domain_name can't be found. This of
course makes mostly sense for trusted domains that can appear and
disappear. And is_files_provider() didn't handle the situation where the
domain pointer was NULL and would directly dereference it.
This commit just adds a NULL check for the domain pointer so that
is_files_provider() returns 'false' if the domain pointer was NULL.
Another alternative might be to check the return value of
find_domain_by_name(), but I don't think it's worth the trouble.
