Fix the documentation for QCA_WLAN_VENDOR_ATTR_CONFIG_UDP_QOS_UPGRADE

The documentation for the QCA_WLAN_VENDOR_ATTR_CONFIG_UDP_QOS_UPGRADE
attribute had incorrectly specified the value of 0 (corresponding to BE)
to disable the QoS upgrade. BK (1) is a lower priority AC compared to BE
and if BE is used to disable the upgrade, there would be no possibility
for configured UDP AC upgrade to replace BK-from-DSCP with BE. Thus,
correct this by specifying that the value of BK (1) is used to disable
this UDP AC upgrade.
