[PATCH] siggen: Fix check calculation problem with file_checksums

[Richard Purdie <richard.purdie@linuxfoundation.org>]

When I enabled debugging of the checksum code, I found the value calculated
from siginfo/sigdata files for do_fetch tasks never matched. This was due
to an error in the way the data was being stored for these, it wasn't ordered
correctly. This patch fixes things so the checksums calculated from
siginfo/sigdata files is correct when file checksums are present.
