[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.
