[RFC PATCH v2 01/10] get_maintainer: Survive querying missing files

[Nikolai Kondrashov]

Do not die, but only warn when scripts/get_maintainer.pl is asked to
retrieve information about a missing file.

This allows scripts/checkpatch.pl to query MAINTAINERS while processing
patches which are removing files.
