Johan Torp e5e29ccdad Fixed intermittent launch failures when cook-on-the-fly is used. ...

A timeout deletes target devices if they fail to respond in 7.5s. The timeout logic was flawed and triggered when the device manager wasn't pumped for 7.5s - even though ping responses came in very quickly. The new logic clears the timeout on a ping response.

Note that there is still a >10s long editor freeze during which the network filesystem seems to clear its cache. There is LogNetworkPlatformFile log spam like below during the freeze:
  Deleting cached file: ... Module.RawInput.gen.cpp
  Deleting cached file: ... Module.RawInput.gen.cpp.obj
  Deleting cached file: ... Module.RawInput.gen.cpp.old
  Deleting cached file: ... Module.RawInput.gen.cpp.txt
  Deleting cached file: ... UE4Editor-RawInput.exp
  Deleting cached file: ... UE4Editor-RawInput.lib

Bonus drive-by changes: Fixed a  memory leak and aligned up some allocations.
