Structs rx_desc_92d and rx_fwinfo_92d will not work for big endian
systems.
Delete rx_desc_92d because it's big and barely used, and instead use
the get_rx_desc_rxmcs and get_rx_desc_rxht functions, which work on big
endian systems too.
Fix rx_fwinfo_92d by duplicating four of its members in the correct
order.
Tested only with RTL8192DU, which will use the same code.
Tested only on a little endian system.
