prov/efa: Init util_domain with correct lock type

Previously, the EFA provider was initializing the util_domain lock to
always be an OFI_LOCK_MUTEX.  This is no longer required if the
threading model is FI_THREAD_DOMAIN_RELAXED.  Initialize domain lock to
be a NOOP when domain threading model is FI_THREAD_DOMAIN_RELAXED.
