Routine Description:
This function deletes all of the storage associated with a device
extension, disconnects from the timers and interrupts and then deletes the
object. This function can be called at any time during the initialization.
Arguments:
Adapter - Supplies a pointer to the device extesnion to be deleted.
Return Value:
None.
