iwlwifi build warning on mips64

Hi folks,

looks like I'm hitting this on a mips64 build:

drivers/net/wireless/intel/iwlwifi/pcie/trans.c:1093: warning: "CAUSE" redefined

Throw an IWL_ before it, maybe?

Oh, right, I think that came up before and I dropped the ball on it, sorry. I'll add something.
