[PATCH] i386: cleanup after cpu_gdt_descr conversion to per-cpu data

With cpu_gdt_descr having been converted to per-CPU data, the old object
(in head.S) no longer needs to reserve space for each CPU's instance.  With
cpu_gdt_table not being used for CPU 0 anymore, it doesn't seem to need
page alignment (or if in fact there is a need for it to retain that
alignment, the whole object should go into .data.page_align).
