Bug: 169662280
The timing of dumpstate to enable diag_mdlog is too marginal to
diag_mdlog process exiting. The starting of diag_mdlog would fail if
diag_mdlog process still exists. Change is to leave some time for
diag_mdlog process to exit before it is enabled again by modifying the
system property vendor.sys.modem.diag.mdlog to true.
