qcacld-3.0: Out of bound access while fetching disabled ml links

Host driver tries to fetch info of disabled ML links from
pm_disabled_ml_links by passing arrays to fill vdev_id_list,
freq_list and ml_idx list. Disabled + enabled links together can't be
more than MAX_NUMBER_OF_CONC_CONNECTIONS from functionality perspective.
But static analyzer tool complains that there are chances for out of
bound access of the given arrays while filling the indexes. Add checks to
avoid any such possible out bound access.
