__hci_cmd_sync() sets skb->packet_type as 0x01 whereas btmrvl_send_sync_cmd() sets it as 0xfe.
But the firmware handles both 0x01 and 0xfe tx packets in similar way. Therefore we can replace btmrvl_send_sync_cmd() with __hci_cmd_sync().

I will send a v2 for this patch shortly. Later on we will send out a cleanup patch for other existing commands that are using btmrvl_send_sync_cmd().

Thanks,
Bing
