Sergey Senozhatsky de6fcbdb68 printk: convert the rest to printk-safe
This patch converts the rest of logbuf users (which are
out of printk recursion case, but can deadlock in printk).
To make printk-safe usage easier the patch introduces 4
helper macros:
- logbuf_lock_irq()/logbuf_unlock_irq()
  lock/unlock the logbuf lock and disable/enable local IRQ

- logbuf_lock_irqsave(flags)/logbuf_unlock_irqrestore(flags)
  lock/unlock the logbuf lock and saves/restores local IRQ state
