[PATCH] libertas: region code values specified as 8bit

Browse Source 
This patch strips away possible mess in regioncode (eg. on my card - 88W8305
chipset - I get 0x3031 instead of expected 0x0031 and as a result the driver
defaults to USA region which is obviously incorrect). Following patch fixes
the issue.
