[PATCH] b4: Remove temporary directory on "missing mbox" error

[PATCH] b4: Remove temporary directory on "missing mbox" error

[Kyle Meyer]

As of 30defdb (b4: Clean up temporary directories by default,
2020-09-27), piem-b4-am-from-mid is supposed to clean up its temporary
directory unless piem-b4-keep-temp-directory is non-nil.  That commit,
however, missed an error case where the cleanup function needs to be
triggered.
