PPP mdm_init takes a lot of time and thus ping does not respond for long

The disconnection may be improper (for example, without proper close, the debugger is restarted) due to which the modem is in improper state and the mdm_init does not get fast initialization sequence. When the modem is powered off and on or once the connection is established after long time and properly closed, it will connect very fast from next time.
