[U-Boot] [PATCH v2 3/5] tools: patman: Generate cover letter correctly when 'END' is missing

[Bin Meng]

If 'END' is missing in a 'Cover-letter' section, and that section
happens to show up at the very end of the commit message, and the
commit is the last commit of the series, patman fails to generate
cover letter for us. Handle this in CloseCommit of patchstream.

Changes in v2:
- Update commit message to explain when such case is hit
- Reset in_section, skip_blank and section variables too
