__parse_profiles_dir(): drop obsolete fallback code as apparmor_parser can skip incorrect profiles on its own
When playing with #147 I noticed that manually running apparmor_parser on my setup takes 2 minutes while using init.d/apparmor script takes over 4 minutes.
That's because if apparmor_parser returns non zero status then script tries to load all apparmor profiles again.
That has nasty results:
- time doubles
- tons of errors that profiles are already loaded
apparmor_parser these days seems to just skip invalid profiles (I've put garbage into profile one and it loaded all other profiles nicely).
So it makes sense to drop that old code.
