[PATCH] iw: fix incorrect bit shifting in print_ht_mcs

["John W. Linville" <linville@tuxdriver.com>]

From: "John W. Linville" <linville@tuxdriver.com>

>From a Coverity run on version 3.10:

iw-3.10/util.c:569:result_independent_of_operands –
	"mcs[10] >> 8" is 0 regardless of the values of its operands. This occurs as the bitwise first operand of '&'.

This seems more like what was intended...
