staging: rtl8723au: Remove unused pointer in rtw_wdev_free()

Pointer 'pwdev_priv' in function rtw_wdev_free() is unused - thus remove it.

---
v2: Resend after v1 failed to apply

* rebased against staging-next - commit 09c3fbba (staging: rtl8188eu:
Remove 'u8 *pbuf' from struct recv_buf)
* fixed mua: no multipart, 7bit text/plain us-ascii

Compile tested and applies against branch staging-next of tree git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
