cherry-pick: wifinative jni: check array length for trackSignificantWifiChange

params.ap is an array with length MAX_SIGNIFICANT_CHANGE_APS == 64
We should check that params.num_ap does not exceed this value,
otherwise this could be a stack overflow security vulnerability.

CTS test is not available because  CTS test doesn't have the
privilege to access system API.
