cifs: fill TRANS2_QUERY_FILE_INFO ByteCount fields

Browse Source 
Currently the trans2 ByteCount field is incorrectly left zero in
TRANS2_QUERY_FILE_INFO info_level=SMB_QUERY_FILE_ALL_INFO and
info_level=SMB_QUERY_FILE_UNIX_BASIC requests. The field should properly
reflect the FID, information_level and padding bytes carried in these
requests.

Leaving this field zero causes such requests to fail against Novell CIFS
servers. Other SMB servers (e.g. Samba) use the parameter count fields
for data length calculations instead, so do not suffer the same fate.
