qcacld-3.0: Fix roam scoring weightage ini configuration

To ensure the total weigtage of various factors doesn't exceed
100, there is a check in mlme_init_scoring_cfg(). If the total
weightage for roam score exceeds 100, the default values are
pushed for the weight configs.

In this computation, the enable/disable value is also added,
which results in configuration only upto 99%. Fix this weight
configuration and remove the enable flag value addition to the
total weight.
