wl12xx uses a single probe response template, regardless of
the probe request.
However, the P2P spec forbids including the p2p ie in some
cases (e.g. the probe request didn't include the p2p ie).

The fw responds only to probe requests that don't
include the p2p ie, and passes up probe requests that
include them (the supplicant will answer them).

Thus, strip the p2p ie from the probe response template.

When we are scanning for the wildcard SSID in a scheduled scan, we

results.
Signed-off-by: NLuciano Coelho <coelho@ti.com>

The wl12xx firmwares support multiple SSIDs in a single sched_scan
run.  This patch implements support for it.

We use three different types os sched_scan: FILTER_ANY (ie. not
filtering, only wildcard SSID in the probe_reqs); FILTER_LIST (ie. send out
probe_reqs with the specified SSIDs and only report if they are
found); and FILTER_DISABLED (ie. send out probe_reqs with the
specified SSIDs, but report anything found).

Since we still don't have proper filter support in nl80211/cfg80211
yet, we cannot use filters when the wildcard SSID is used.  Thus, we
will not filter anything if the wildcard SSID is specified.
