{arch,cpu}/x86, drivers/intel: Restore cpu_index error handling
Previously cpu_index() always succeeded, but since commit 095c931
(src/arch/x86: Use core apic id to get cpu_index()) it is now possible
for it to indicate an error by returning -1. This commit adds error
handling for all calls to cpu_index(), and restores several checks that
were removed in commit 7c712bb (Fix code that would trip -Wtype-limits)
but are now needed.
