Subject: [PATCH] x86, ioapic: Get rid of needless check and simplify
 ioapic_setup_resources()

alloc_bootmem() already panics on allocation failure. There is
no need to check the result.

Also there is a way to unbind global variable from its body and
use it as a parameter which allow us to simplify
ioapic_init_mappings as well -- "for" cycle already uses
nr_ioapics as a conditional variable and there is no need to
check if ioapic_setup_resources was returning NULL again.
