update-ref --stdin: narrow scope of err strbuf
Making the strbuf local in each function that needs to print errors
saves the reader from having to think about action at a distance,
such as
* errors piling up and being concatenated with no newline between
them
* errors unhandled in one function, to be later handled in another
* concurrency issues, if this code starts using threads some day
No functional change intended.
