In Windows 2012R2, Hyper-V virtual machine export does not work with samba 4.6 share.

Steps to reproduce

1. In Hyper-V, select export VM, select samba share as destination storage
2. Export failed.

Seems regression bug, VM export works with samba 4.5

./source3/smbd/smb2_ioctl_filesys.c

        if ((fsp->conn->fs_capabilities & FILE_FILE_COMPRESSION) == 0) {
                DEBUG(4, ("FS does not advertise compression support\n"));
                return NT_STATUS_INVALID_DEVICE_REQUEST;
        }
