LU-15671 ost: remove REP_MBITS from OST_CONNECT2_SUPPORTED

Remove the OBD_CONNECT2_REP_MBITS flag from the OST_CONNECT2_SUPPORTED
mask on the OST that was accidentally included in a backported patch.
If newer clients that have support for REP_MBITS (e.g. 2.15.x) try to
recover with the 2.14.0-ddn91+ OSS, they will loop endlessly since
they are not exchanging the right information in the replay RPC/reply.

Test-Parameters: trivial
