Add new mechanism for stopping FP HIDL after several times init fail. This prevents the case of FP HIDL keeping trying to do init process and raising CPU usage when sensor totally dead. After limited times init retry fail (default 10 times), FP HIDL will be stopped. init-fingerprint-sh is for stopping fps_hal after init retry fail serval times. It keeps running until max init retry or fps_hal running successfully. vendor.fps_hal restarts until max init retry times fail. Test: build pass and FP functionaily are good. Test: init process will be stopped after limited times retry fail Bug: 111710758 Change-Id: I8a19bdd351e5d712f8e23c6a0849acb1771e61e5 Signed-off-by: emilchung <emilchung@google.com>
