Details:

The PXE TFTP API only allows one open connection at any one time. The PXE
module in GRUB2 has code to handle this in some places, but in other places
(grub_pxefs_open and grub_pxefs_close) it is not handled, causing errors. For
example, when I try to insert the multiboot module from PXE, that wants to
insert the _multiboot module, resulting in the PXE call failing because 2
connections are being made.

I've attached a patch which handles this properly in grub_pxefs_open() and
grub_pxefs_close(). With these changes made I can successfully load GRUB2 from
PXE, and boot a kernel.
