LU-13356 client: don't use OBD_CONNECT_MNE_SWAB

LU-13356 client: don't use OBD_CONNECT_MNE_SWAB

OBD_CONNECT_MNE_SWAB is equal to OBD_CONNECT_MDS_MDS, and
it was used at MGC client in past for mne swabbing during interop.
Right now it is interpreted at MGS like OBD_CONNECT_MDS_MDS and skip
these clients from eviction and lock canceling after timeout.

Fixes: 1bdc4fd0594e ("LU-6307 obdclass: distinguish MGC/MDT connection properly")
