xen/arch/*: add struct domain parameter to arch_do_domctl
Since the arch-independent do_domctl function now RCU locks the domain
specified by op->domain, pass the struct domain to the arch-specific
domctl function and remove the duplicate per-subfunction locking.
This also removes two get_domain/put_domain call pairs (in
XEN_DOMCTL_assign_device and XEN_DOMCTL_deassign_device), replacing
them with RCU locking.
