roam_band_bitmap is updated based on the vendor command from
userspace, when NCHO band configuration is received.
Update the MLO support_link_band sent to firmware as part of the
RSO commands to intersect the user configured roam_band_bitmap
value.
This will restrict the firmware to advertise only those bands
sent in the WMI_ROAM_MLO_CONFIG_CMDID command, and firmware
will advertise only links corresponding to the configured
bands in the reassociation request.
WMI_ROAM_MLO_CONFIG_CMDID will be sent when
QCA_ATTR_ROAM_CONTROL_BAND_MASK attribute is received in roaming
subcmd: QCA_WLAN_VENDOR_ROAMING_SUBCMD_CONTROL_SET as part of
NCHO set band, since RSO stop, followed by start is sent during
set band to update PCL to firmware
