[PATCH] uml: fix failure path after conversion

Little fix for error paths in this code.

- Some bug come from conversion to os-Linux (open() doesn't follow the
  kernel -errno return convention, while the old code called os_open_file()
  which followed it).  This caused the wrong return code to be printed.

- Then be more precise about what happened and do some whitespace fixes.
