ath5k: fix off-by-one in pilot magnitude mask
If the symbol offset is 46, it will be counted in both the third and fourth bytes of the mask, and in this case the shift will be negative which can pollute high order bits in the mask. This may negatively impact OFDM symbol detection. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
