qcacmn: create qdf_nbuf_cb definition for win and mcc

ソースを参照 
WIN and MCC shared a common definition od qdf_nbuf_cb
considering that there are various fields which are
not common it is decided to have 2 different definitions
for WIN and MCC. in case of WIN he per pkt cycles will
be significantly reduced in RX path.

* struct qdf_nbuf_cb - network buffer control block contents (skb->cb)
* - data passed between layers of the driver.
*
* Notes:
* 1. Hard limited to 48 bytes. Please count your bytes
* 2. The size of this structure has to be easily calculable and
* consistently so: do not use any conditional compile flags
* 3. Split into a common part followed by a tx/rx overlay
* 4. There is only one extra frag, which represents the HTC/HTT header
* 5. "ext_cb_pt" must be the first member in both TX and RX unions
* for the priv_cb_w since it must be at same offset for both
* TX and RX union
* 6. "ipa.owned" bit must be first member in both TX and RX unions
* for the priv_cb_m since it must be at same offset for both
* TX and RX union.
