Log message:
Encrypt swap pages "inline" instead of going through a bounce buffer.  This
means we no longer need to reserve bounce pages for the pagdaemon.  Instead
we can use the complete set of psegs to swap out pages.  Note that there is
another important consequence of this diff.  Before the old page remaines
unencrypted and on the inactive queue, where it will sit until the
pagedaemon runs again and kills it.  With this diff, pages will be freed
as soon as the I/O completes.  This is probably an improvement in itself.

This is simplified version of a diff posted by mpi@ earlier this year.
These simplifications were possible because we no longer bounce pages to
meet DMA constraints in the swap code.
