Hi,

While debugging a somewhat related issue, I ran into two issues I
believe can cause the hypervisor to write garbage to the pipe.

This was find by visual inspection and is only slightly tested.  It
seems to partially some the problems my test case shows.

Please, let me know what you think

  um: ubd: Prevent buffer overrun on command completion
  um: ubd: Retry buffer read on any kind of error
