[PATCH] cfg80211: fix cmp_hidden_bss

[Johannes Berg <johannes@sipsolutions.net>]

From: Johannes Berg <johannes.berg@intel.com>

The cmp_bss() comparator function uses memcmp() to
compare the SSID. This means that cmp_hidden_bss()
needs to similarly return a number bigger than zero
(use 1) instead of -1 when ie1 is bigger than ie2,
which is the case if an ie2 byte is non-zero.
