[PATCH] wireless: correct dump of WPA IE

In net/ieee80211/softmac/ieee80211softmac_wx.c, there is a bug that
prints extended sign information whenever the byte value exceeds
0x7f. The following patch changes the printk to use a u8 cast to limit
the output to 2 digits. This bug was first noticed by Dan Williams
<dcbw@redhat.com>. This patch applies to the current master branch
of the Linville tree.
