rt2x00: provide separate information about TXWI & RXWI sizes
On new 2800 hardware sizes of TXWI & RXIW can be different than TXD & RXD sizes, so we need to difference between them. Let's define winfo_size as size of in buffer descriptor (TXWI & RXWI), and desc_size of as size of additional descriptor - in separate DMA coherent buffer for PCI hardware (TXD & RXD) and yet another in buffer descriptor for USB hardware (TXINFO & RXINFO). Change is rt2x00 wild, but should affect only 2800 driver. Patch also fix beaconing for 5592usb AP mode.
