[PATCH 1/2 V2 3.18] rtlwifi: rtl8821ae: Fix 5G detection problem

[Larry Finger]

The changes associated with moving this driver from staging to the regular
tree missed one section setting the allowable rates for the 5GHz band.

This patch is needed to fix the regression reported in Bug #88811
(https://bugzilla.kernel.org/show_bug.cgi?id=88811).

    He's also suggested spaces around << in his example

    The kernel style generally assumes spaces around operators, and it would 
only be consistent with the other code in the vicinity if you added them...
