Subject: [PATCH 02/32] staging/lustre: KEY_DEFAULT/MAX_COOKIESIZE key is unused, remove them

From: Oleg Drokin <green@...uxhacker.ru>

Also remove the lmv and mdc infrastructure to query these keys.
In fact this whole "unlink cookies" thing becomes irrelevant
with newer servers, but since we still retain 2.[123] servers
commpatibility, we cannot completely remove all traces of it yet.
