mwifiex: fix cmd_skb headroom decreasing issue
Before calling host_to_card() to send the cmd to firmware, we use skb_push() to add 4 bytes SDIO interface header at the start of the data buffer. Since cmd_skb data structure will be re-used at a later time, we need to restore its headroom by removing the 4 bytes header.
