3.16.65-rc1 review patch. If anyone has any objections, please let me know.

From: "Yan, Zheng" zyan@redhat.com
commit 3c1392d4c49962a31874af14ae9ff289cb2b3851 upstream.
Updating mseq makes client think importer mds has accepted all prior cap messages and importer mds knows what caps client wants. Actually some cap messages may have been dropped because of mseq mismatch.
If mseq is left untouched, importing cap's mds_wanted later will get reset by cap import message.
