lockdep: remove extra "irq" string

Browse source 
Impact: clarify lockdep printk text

print_irq_inversion_bug() gets handed state strings of the form

  "HARDIRQ", "SOFTIRQ", "RECLAIM_FS"

and appends "-irq-{un,}safe" to them, which is either redudant for *IRQ or
confusing in the RECLAIM_FS case.
