iwlagn: fix scan tx antenna setting on 5Ghz band
Looks that we do not set correctly antennas when scanning
on 5Ghz band and when bluetooth is enabled, because
priv->cfg->scan_tx_antennas[band] is only defined for
IEEE80211_BAND_2GHZ.
To fix we check band before limiting antennas to first one.
This allow to remove hard coded cfg->scan_tx_antennas[band].
