[IA64] Delete iosapic_free_rte()

I did it on purpose (and gave the warning a miss...) and I consider
iosapic_free_rte() is no longer needed.
I decided to remain iosapic_rte_info to keep gsi-to-irq binding
after device disable. Indeed it needs some extra memory, but it
is only "sizeof(iosapic_rte_info) * <the number of removed devices>"
bytes and has no memory leak becasue re-enabled devices use the
iosapic_rte_info which they used before disabling.
