rtl8xxxu_set_basic_rates() sets the wrong initial RTS rate. It sets the next higher rate than the one it should set, e.g. 36M instead of 24M. The while loop was supposed to find the index of the most significant bit which is 1, but it was copied incorrectly from the vendor driver. Use __fls() instead.
