I thought about the error path, but I realized the error handling code
couldn't be simpler. There is only one error, namely ENOENT, which
warrants no error path. As 'err' variable was used, you were forced to
reset it to zero seven months ago. Again you were forced to reset it to
zero six months ago. As you were doubly forced, finally I came up with
this idea of getting rid of the unnecessary variable.

Also the error handling in the patch is consistent with the way earlier
portion of the function definition does.

Thank you for reviewing. This is a rather trivial patch. If patches like
this one are not compelling enough for acceptance, that's fair enough.
