wifi: brcmsmac: LCN PHY code is used for BCM4313 2G-only device

[ Upstream commit c636fa85feb450ca414a10010ed05361a73c93a6 ]

The band_idx variable in the function wlc_lcnphy_tx_iqlo_cal() will
never be set to 1 as BCM4313 is the only device for which the LCN PHY
code is used. This is a 2G-only device.
