EpdgTunnelManager: Handle IAE on applying transforms

- When IKE session is closed (in a concurrent thread) immediately
after Child session transforms are created, IpSecService may throw
an IllegalArgumentException when TunnelManager attempts to apply
the transforms.
- This race condition cannot be protected by synchronization, so
we handle the exception and defensively attempt to (re)close the
IKE session.
