Grub fails to boot from internal TFTP server when loading more than 3 initrd files.

Grub first opens a session to the TFTP server for every initrd file and
retrieves only the file size for all.
Then it wants to download the content using the old sessions which are
already expired.

Increasing the maximum number of session of the internal TFTP
server avoids this issue.

The error message reads as following:
error: timeout reading
`/boot/ISO.ROOT/BOOTMGR'.

This looks sane.  And while slirp has the maintainer, he appears to be
inactive, so applying it to -trivial.  Thank you!
