staging: wfx: avoid namespace contamination

Browse Source 
tx_policy_init() was already defined in driver cw1200. So, compilation
failed when wfx and cw1200 were both built-in.

In order to keep a coherent naming scheme, this patch prefixes all
"tx_policy_*" functions with "wfx_".

Fixes: 9bca45f3d6 ("staging: wfx: allow to send 802.11 frames")
