Add new field nontransmitting_vif_count in struct ath11k_vif which
keeps track of non-transmitting interfaces associated with a
transmitting interface when MBSSID is enabled.
The count is decremented when WMI vdev down is invoked and incremented
when WMI vdev up is invoked.
Use this field to set the profile index and total profile count during
WMI vdev up operation.
