LU-10005 osp: cache non-exist EA

OSP should also cache non-exist EA, otherwise
it will keep sending RPC to try to get remote
non-exist EA.

So if default stripe EA does not exist on root
MDT, file creation on non-root MDT will always
try to send extra OSP RPC to get the EA.

This patch also fixes a LFSCK bug that may cause
the LFSCK repaired items to be counted repeately.
