RDMA/efa: Fix setting of wrong bit in get/set_feature commands

RDMA/efa: Fix setting of wrong bit in get/set_feature commands

When using a control buffer the ctrl_data bit should be set in order to
indicate the control buffer address is valid, not ctrl_data_indirect
which is used when the control buffer itself is indirect.
