lockdep: Fix trace_[soft,hard]irqs_[on,off]() recursion

Commit:

  1efc5da3

: [PATCH] order of lockdep off/on in vprintk() should be changed

explains the reason for having raw_local_irq_*() and lockdep_off()
in printk(). Instead of working around the broken recursion detection
of interrupt state tracking, fix it.
