audit: Rename enum audit_state constants to avoid AUDIT_DISABLED redefinition

AUDIT_DISABLED defined in kernel/audit.h as element of enum audit_state
and redefined in kernel/audit.c. This produces a warning when kernel builds
with syscalls audit disabled and brokes kernel build if -Werror used.
enum audit_state used in syscall audit code only. This patch changes
enum audit_state constants prefix AUDIT to AUDIT_STATE to avoid
AUDIT_DISABLED redefinition.
