There's currently a bug with the way kernel-doc script
counts line numbers that can be seen with:
$ ./scripts/kernel-doc -rst -enable-lineno include/linux/math64.h >all && ./scripts/kernel-doc -rst -internal -enable-lineno include/linux/math64.h >int && diff -U0 int all

This is happening with perl version 5.30.3, but I'm not
so sure if this is a perl bug, or if this is due to something
else.
In any case, fixing it is easy. Basically, when "-internal"
parameter is used, the process_export_file() function opens the
handle "IN". This makes the line number to be incremented, as the
handler for the main open is also "IN".
Fix the problem by using a different handler for the
main open().
While here, add a missing close for it.
