s3-printing: fix cups pcap reload with no printers
cups_async_callback() is called to receive new printcap data from a child process which requests the information from cupsd. Newly received printcap information is stored in a temporary printcap cache (tmp_pcap_cache). Once the child process closes the printcap IPC file descriptor, the system printcap cache is replaced with the newly populated tmp_pcap_cache, however this only occurs if tmp_pcap_cache is non null (has at least one printer). If the printcap cache is empty, which is the case when cups is not exporting any printers, the printcap cache is not replaced resulting in stale data. https://bugzilla.samba.org/show_bug.cgi?id=7915 Signed-off-by: Andreas Schneider <asn@samba.org>
