commit a88126d6e8577a9e0b6196acdee70633d0e06259
Author: David Disseldorp <ddiss at suse.de>

s3-printing: remove pcap_cache_loaded asserts
pcap_cache_loaded() assertions were added to the (re)load_printers()
functions, to ensure the caller had called pcap_cache_reload() prior to
reloading printer shares.
The problem is, pcap_cache_loaded() returns false if the the pcap_cache
contains no printer entries. i.e. pcap_cache_reload() has run but not
detected any printers.
Remove these assertions, correct call ordering is already enforced.

The last 3 patches address bug #7836 (A newly added printer isn't visbile to
clients).
