  Changed paths:
    M src/lib-index/mail-cache.c

  Log Message:
  -----------
  lib-index: Don't log error on dovecot.index.cache delete if it doesn't exist

For example if a cache is marked as corrupted and there is no cache, it's
not really an error that it doesn't exist.

Fixes:
Error: unlink(.../dovecot.index.cache) failed: No such file or directory (in mail-cache.c:29)
