an initial fix for handling sparse files in smbd

This gets my test code working, where we previously failed with files
above 20G in size.

I'm still not completely happy with this. There are just too many
fields in trans2.c that we don't fill in.
(This used to be commit 7dfdb456d4c9bcf6ecb1f7e5c5e79989f95e5627)
