This patch basically avoids out of memory issue caused by our driver. It also solves the problem when dev_alloc_skb fails by other reasons. When dev_alloc_skb is failed in mwifiex_usb_submit_rx_urb(), we skip submitting that particular URB and "ctx->skb" remains NULL. Later when pending packets are being consumed in Rx work queue, "if_ops.submit_rem_rx_urb()" call takes care of submitting the URB skipped previously. Please let me know you have any doubts.
