Instead of converting it to a bogus error code -1, we should
return the original error code from lower layer driver. This
error code will be printed so it may give user some clues on
what has happened.

We know 'firmware' is non-NULL from the beginning of mwifiex_prog_fw_w_helper,
remove all !firmware paths from the rest of the function.

This patch adds support for multiple TX queues inside mwifiex
driver. Four different queues according to WMM access categories
are defined for each virtual interface. When a packet is
received from netdev for transmission, tx pending count for
particular queue is incremented and if tx pending count has
reached upper water-mark, this queue is stopped instead of
stopping all queues. Similarly when a packet is successfully
transmitted from device, tx pending count is decremented per
queue and if pending count falls below lower water-mark, queue
operations are again resumed. This ensures that not all
tranmission is blocked if traffic with particular TOS value
suddenly increases.

Also wake all queues after association/IBSS_join/uAP_BSS_start
to enable traffic on all queues.

skb allocated during initialisation is reused for receiving
commands/events by USB interface. We miss to reset skb->data in
failure cases. This patch takes care of it.

This patch ensures uniformity in event skb sent by interface code
(USB/PCIe/SDIO) which automatically fixes following bugs.

1) For USB interface, same buffer is reused for receiving cmd and
events from firmware. While handling events, we perform
skb_pull(skb, 4) to remove event header. Corresponding skb_push()
call is missing while submitting the buffer.
2) For PCIe interface, event skb is passed with event header.
Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH
will not work for PCIe, as they assume event skb points to event body.
