Removal of dead code and adding log messages to make it easier

for debugging

- Add more logging using ALOGD(..) for function dispatchSmsWrite,
dispatchDial, dispatchSIM_IO, dispatchSIM_APDU, dispatchCallForward,
dispatchRaw and dispatchCdmaSmsAck. To make it easier for debugging.

- Remove commented log message inside wakeTimeoutCallback () function
and remove the else clause as it's dead not used for anything.

- Modify log message inside removeFromList and removeWatch using +
and - to make it consistent with the other log message.
