Yan, Zheng 9797226bf6 ceph: don't update importing cap's mseq when handing cap export 
commit 3c1392d4c4 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.
