btrfs-progs: inspect logical-resolve: Set correct error value 

Reset ret value to zero after snprintf(), which returns the number
of written chars. Otherwise non-zero value returns after command
success with -P option. Also set return value from __ino_to_path_fd() to
reflect the final status for default behavior.
