drbd: re-add lost conf_mutex protection in drbd_set_role

Browse source

The conf_update mutex used to be held while clearing the
net_conf->discard_my_data flag inside drbd_set_role.

It was moved into drbd_adm_set_role with
    drbd: allow parallel promote/demote actions
but then replaced at that location by the newly introduced adm_mutex with
    drbd: Fix a potential deadlock in drbdsetup, introduce resource->adm_mutex

And I simply forgot to put it back in at the original location.
