tmem: Retire XEN_SYSCTL_TMEM_OP_[SET_CAP|SAVE_GET_CLIENT_CAP]
It is not used by anything. Its intent was to complement
the 'weight' attribute but there hadn't been any request for this.
If there is a need to resurface it, it can be integrated back
via the XEN_SYSCTL_TMEM_SET_CLIENT_INFO introduced in
"tmem/libxc: Squash XEN_SYSCTL_TMEM_OP_[SET|SAVE].."
