[rfc 1/4] x86: irq.c - tiny cleanup

[Cyrill Gorcunov <gorcunov@openvz.org>]

[-- Attachment #1: x86-irq-cleanup --]
[-- Type: text/plain, Size: 1350 bytes --]

Impact: cleanup

1) guard ack_bad_irq with printk_ratelimit since there is no
   guarantee we will not be flooded one day
2) use pr_emerg helper
