[PATCH ghak138 v2 4/4] audit: move audit_return_fixup before the filters

[Richard Guy Briggs]

The success and return_code are needed by the filters.  Move
audit_return_fixup() before the filters.  This was causing syscall
auditing events to be missed.

Fixes: 12c5e81d3fd0 ("audit: prepare audit_context for use in calling contexts beyond syscalls")
