[PATCH] Force data attach when data is re

 enabled after carrier-detatch.

Some networks detach from PS when data is disabled for a time
period. DcTracker handles this scenario using mAutoAttachOnCreation
flag. However DcSwitchStateMachine doesnot execute requests until
PS is attached. This leads to no data in case of WIFI disconnect.
So extend the same logic to DcSwitchStateMachine.
