x86: Remove timeouts from INIT-SIPI-SIPI sequence when using x2apic.

Some of the timeouts are pointless since they're waiting for the ICR
to ack the IPI delivery and that doesn't happen on x2apic.
The others should be benign (and are suggested in the SDM) but
removing them makes AP bringup much more reliable on some test boxes.
