In multi-mds, the 'caps' debugfs file will have duplicate ino,
add the 'mds' column to indicate which mds session the cap belongs to.

is already set, it can be returned directly without the logic behind it.
But the current logic doesn't return directly because the condition
'mode == USE_AUTH_MDS', and sometimes frag's mds is not equal to
cap's session mds, which then causes the request to be resent.

kernel client is still sending write,startsync.
that startsync is a no-op (has been for years) and can probably be removed
