smb3: move defines for ioctl protocol header and SMB2 sizes to smbfs_common
The definitions for the ioctl SMB3 request and response as well as length of various fields defined in the protocol documentation were duplicated in fs/ksmbd and fs/cifs. Move these to the common code in fs/smbfs_common/smb2pdu.h Reviewed-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
