Konstantin Belousov 8fba5348fc amd64: ensure that curproc->p_vmspace pmap always matches PCPU 
curpmap.

When performing context switch on a machine without PCID, if current
%cr3 equals to the new pmap %cr3, which is typical for kernel_pmap
vs. kernel process, I overlooked to update PCPU curpmap value.  Remove
check for %cr3 not equal to pm_cr3 for doing the update.  It is
believed that this case cannot happen at all, due to other changes in
this revision.

Also, do not set the very first curpmap to kernel_pmap, it should be
vmspace0 pmap instead to match curproc.

Move the common code to activate the initial pmap both on BSP and APs
into pmap_activate_boot() helper.
