Remove attemptDeadServiceRecovery() from TagTechnology's.

attemptDeadServiceRecovery() is a hack to recover from NfcService dying. It
should be a rare event, and is only needed in NfcAdapter which is a long-lived
object.

TagTechnology objects are transient, it is acceptable for them to go stale
when NFC service dies. Lets not complicate the code with recovery for a rare
event.
