You should not have removed this line...

... we need keep_name for this error message.

Warning: I did not test the failure path; but I made sure that these

Subject: [PATCH] index-pack: Set keep_name if a new keep file was allocated

6e180cdc (Make sure objects/pack exists before creating a new pack,
2009-02-25) simplified the code in this area, but it also extended an
error message to include the file name that caused the error. However,
one code path did not set file name correctly.
