Strangely Windows servers do not appear to check the open-time granted
access on the source file. This behaviour matches what is documented in
[MS-SMB2] 3.3.5.15.6 Handling a Server-Side Data Copy Request, where
only the destination file is checked for open-time granted read and
write access.

I'll drop the src_fsp check for now, dest_fsp will be checked for read
and write access. New round of patches with a bunch more torture tests
is on its way.

Cheers, David
