pxelinux: fix the handling of KeepPXE
KeepPXE was broken in 3.74, because we tried to use both bits 0 and 1,

com32: use xfer_buf_seg as the bounce buffer
We cannot realistically realign comboot_seg without breaking com16
modules (which have the DOS-derived assumption that they own the rest
of low memory.) However, we can use xfer_buf_seg as the com32 bounce
buffer, which allows us to retain the benefit of a 64K-aligned buffer.

core: don't misalign xfer_buf_seg
xfer_buf_seg is used for bulk transfers, and we really don't want
to break it up in order to avoid 64K DMA boundaries.
Note: the same is true for the com32 bounce buffer, which is
real_mode_seg. However, there are hard assumptions in the code that
real_mode_seg is the last segment; those need to be cleaned up, or we
need to verify that xfer_buf_seg can be used as the com32 bounce
buffer.
