LU-537 o2iblnd: support aliased interface

Current kiblnd_create_dev() doesn't allow to dev_get_by_name() to
return NULL (we added this for supporting failover of ib-bonding),
but this can happen for aliased interface, we can fix this by simply
remove the limitation and set kib_dev_t::ibd_can_failover to 0 for
aliased interface.
