net: thunderx: add nicvf_send_msg_to_pf result check for set_rx_mode_task

The rx_set_mode invokes number of messages to be send to PF for receive
mode configuration. In case if there any issues we need to stop sending
messages and release allocated memory.

This commit is to implement check of nicvf_msg_send_to_pf() result.
