cifs: fix bi-directional fsctl passthrough calls

Browse source

SMB2 Ioctl responses from servers may respond with both the request blob from
the client followed by the actual reply blob for ioctls that are bi-directional.

In that case we can not assume that the reply blob comes immediately after the
ioctl response structure.

This fixes FSCTLs such as SMB2:FSCTL_QUERY_ALLOCATED_RANGES
