With the introduction of SMB2_OP_QUERY_WSL_EA, the client may now send 5 commands in a single compound request in order to query xattrs from potential WSL reparse points, which should be fine as we currently allow up to 5 PDUs in a single compound request. However, if encryption is enabled (e.g. 'seal' mount option) or enforced by the server, current MAX_COMPOUND(5) won't be enough as we require an extra PDU for the transform header. Fix this by increasing MAX_COMPOUND to 7 and, while we're at it, add an WARN_ON_ONCE() and return -EIO instead of -ENOMEM in case we attempt to send a compound request that couldn't include the extra transform header.
