Use the VM_ALLOC_INTERRUPT for the page requests when allocating memory
for the bio for swapout write. It allows the page allocator to drain
free page list deeper. As result, a deadlock where pageout deamon sleeps
waiting for bio to be allocated for swapout is no more reproducable in
practice.

Alan said that M_USE_RESERVE shall be ressurrected and used there, but
until this is implemented, M_NOWAIT does exactly what is needed.
