WPS NFC: Remove NFC_RX_HANDOVER_SEL

Browse source 
The newer NFC_REPORT_HANDOVER command is more general version that
handles the cases where NFC_RX_HANDOVER_SEL could potentially have been
used. In addition, with the new WPS NFC design, it is important to
receive the handover request message that was used in the handover in
addition to the select message, so the NFC_RX_HANDOVER_SEL command on
its own would not be sufficient for this.
