wifi: cfg80211: wext: validate chandef in monitor mode
cfg80211_wext_siwfreq() constructs a channel definition for monitor
mode but passes it to cfg80211_set_monitor_channel() without first
validating it with cfg80211_chandef_valid(). This causes a WARN_ON
in cfg80211_chandef_dfs_required() when it receives an invalid chandef.
Add the missing cfg80211_chandef_valid() check before calling
cfg80211_set_monitor_channel() to return -EINVAL early on invalid
channel definitions, consistent with how other callers handle this.
