MFC fix for the panic("vm_thread_new: kstack allocation failed") and
silent NULL pointer dereference in the i386 and sparc64 pmap_pinit()
when the kmem_alloc_nofault() failed to allocate address space. Both
functions now return error instead of panicing or dereferencing NULL.

The reason for MFCing this so late in release cycle is, according to
marius@, because
> it fixes the crashing (though no panic) of the test suite
> of the graphic/OpenEXR port on sparc64. This test suite is run
> (and required to succeed) during the package build and that's
> why portmgr@ bitch about at it as OpenEXR is a dependency of KDE
> which in turn is supposed to end up on the release CD images.
