Revert "x86_64: Quicklist support for x86_64"

This reverts commit 34feb2c83beb3bdf13535a36770f7e50b47ef299.

Suresh Siddha points out that this one breaks the fundamental
requirement that you cannot free page table pages before the TLB caches
are flushed.  The quicklists do not give the same kinds of guarantees
that the mmu_gather structure does, at least not in NUMA configurations.
