LU-13455 ptlrpc: connect to MDT stucks

mdc_ioc_hsm_ct_register() is executed on
IMP_EVENT_ACTIVE event.
If HSM_CT_REGISTER request expires import becomes
disconnected but reconnect can't start because
previous connect waits for completion of
HSM_CT_REGISTER request.

Mark HSM_CT_REGISTER request as no_resend.
