[PATCH] CFQ: use irq safe locking in cfq_cic_link()
If cfq_set_request() is called for a new process AND a non-fs io
request (so that __GFP_WAIT may not be set), cfq_cic_link() may
use spin_lock_irq() and spin_unlock_irq() with interrupts already
disabled.
Fix is to always use irq safe locking in cfq_cic_link()
