smb3: optimize open to not send query file internal info
We can cut one third of the traffic on open by not querying the inode number explicitly via SMB3 query_info since it is now returned on open in the qfid context. This is better in multiple ways, and speeds up file open about 10% (more if network is slow). Reviewed-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>
