xen: avoid calling rcu_lock_*target_domain when an XSM hook exists
The rcu_lock_{,remote_}target_domain_by_id functions are wrappers
around an IS_PRIV_FOR check for the current domain. This is now
redundant with XSM hooks, so replace these calls with
rcu_lock_domain_by_any_id or rcu_lock_remote_domain_by_id to remove
the duplicate permission checks.
When XSM_ENABLE is not defined or when the dummy XSM module is used,
this patch should not change any functionality. Because the locations
of privilege checks have sometimes moved below argument validation,
error returns of some functions may change from EPERM to EINVAL when
called with invalid arguments and from a domain without permission to
perform the operation.
