x86: Convert per-cpu counter icr_read_retry_count into a member of irq_stat

Browse Source 
LAPIC related statistics are grouped inside the per-cpu
structure irq_stat, so there is no need for icr_read_retry_count
to be a standalone per-cpu variable.

This patch moves icr_read_retry_count to where it belongs.
