audit: avoid -Wempty-body warning
gcc warns about an empty statement when audit_remove_mark is defined to nothing: kernel/auditfilter.c: In function 'audit_data_to_entry': kernel/auditfilter.c:609:51: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 609 | audit_remove_mark(entry->rule.exe); /* that's the template one */ | ^ Change the macros to use the usual "do { } while (0)" instead, and change a few more that were (void)0, for consistency.
