hso: remove some dead code
It seems like this function was intended to have special handling for
urb statuses of -ENOENT and -ECONNRESET. But now it just prints some
debugging and returns at the start of the function.
I have removed the dead code, it's still in the git history if anyone
wants to revive it.
