remsim-client: Fix the -k/ --keep-running option
When introducing asynchronous USB support in Change-Id Ic18690b3c2cbc5e99de0665c0b68b7555433b3cd, we accidentially broke the --keep-running behavior, where even a disappearing USB device will not terminate the remsim-client process. Change-Id: I19cca9f7953d61058a36856b2fc4c97a3b93e15d
