LU-665 mds: Reduce MDS-OSS connection flags
Some connection flags MDSs send to OSSs are unnecessary or misleadingly
implying features not (yet) implemented by current MDSs. This patch
removes the following ones:
- OBD_CONNECT_64BITHASH. MDSs don't send MDS_READPAGE or FLD_QUERY
requests to OSSs.
- OBD_CONNECT_BRW_SIZE. MDSs don't do bulk I/O with OSSs.
- OBD_CONNECT_CKSUM. Ditto.
- OBD_CONNECT_FID. MDSs don't support OST FIDs.
