audit: Remove condition which always evaluates to false
After commit 3e1d0bb6224f019893d1c498cc3327559d183674 ("audit: Convert int limit
uses to u32"), by converting an int to u32, few conditions will always evaluate
to false.
These warnings were emitted during compilation:
kernel/audit.c: In function ‘audit_set_enabled’:
kernel/audit.c:347:2: warning: comparison of unsigned expression < 0 is always
false [-Wtype-limits]
if (state < AUDIT_OFF || state > AUDIT_LOCKED)
^
kernel/audit.c: In function ‘audit_receive_msg’:
kernel/audit.c:880:9: warning: comparison of unsigned expression < 0 is
always false [-Wtype-limits]
if (s.backlog_wait_time < 0 ||
The following patch removes those unnecessary conditions.
