mds: remove calculating caps after adding revokes back

The calc_issued() makes no sense and will blindly set the 'issued'
to the 'pending', which is incorrect.

For the cap update msg it will pass the client's 'implemented' caps
to MDS, and MDS will use the 'implemented' to calculate the 'issued'
and 'pending' members and also will adjust the revoke list.

The confirm_receipt() has already correctly calculating the 'issued'
and 'pending' members. And after add the cap back to the revoke list
we should mark it notable, which will move the cap object to the
front of session list.
