pr: don’t use uninitialized var

Found with -flto and --enable-gcc-warnings.
* src/pr.c (getoptarg): Fix misuse of xstrtol, which does not
necessarily set tmp_long on errror, and does not set errno in any
reliable way.  The previous code might access uninitialized
storage; on typical platforms this merely causes it to possibly
print the wrong diagnostic.
