Description

this patch (http://review.whamcloud.com/#change,4940) assumes that most MDS services only need 5K as request buffer size, the only exception is "regular" service which can get large request with LOV EA information.
However, OUT service of DNE can have request size up to 9K, which means we also need to define individual buffer size for OUT.
