smb2_ioctl: add support for FSCTL_SRV_COPYCHUNK_WRITE

FSCTL_SRV_COPYCHUNK can only be used when the client has the copy-chunk
target file open with FILE_WRITE_DATA and FILE_READ_DATA.
FSCTL_SRV_COPYCHUNK_WRITE requires only FILE_WRITE_DATA access on the
target, and is therefore suitable for cp --reflink, which opens the
target file O_WRONLY.
