libsemanage: Always set errno to 0 before calling getpwent()
The manpage explicitly states that:
The getpwent() function returns a pointer to a passwd structure, or
NULL if there are no more entries or an error occurred. If an error
occurs, errno is set appropriately. If one wants to check errno after
the call, it should be set to zero before the call.
Without this, genhomedircon can wrongly return the following:
libsemanage.get_home_dirs: Error while fetching users. Returning list so far.
