lockdep: Provide off case for redundant_hardirqs_on increment

We forgot to provide a !CONFIG_DEBUG_LOCKDEP case for the
redundant_hardirqs_on stat handling.

Manage that in the headers with a new __debug_atomic_inc() helper.

Fixes:

	kernel/lockdep.c:2306: error: 'lockdep_stats' undeclared (first use in this function)
	kernel/lockdep.c:2306: error: (Each undeclared identifier is reported only once
	kernel/lockdep.c:2306: error: for each function it appears in.)
