Put STATE_LOCK_OWNER_9P under _USE_9P

Commit 56da7504cd09c67c41c59aa97f8fec8d2b3848a5 removed
STATE_LOCK_OWNER_9P from #ifdef _USE_9P.  This necessiated changes in
many switch statements and they don't look right! One of the examples is
listed below which imply that case STATE_LOCK_OWNER_9P returns
ht_nfs4_owner if _USE_9P is not defined.

        case STATE_LOCK_OWNER_9P:
                return ht_9p_owner;
        case STATE_OPEN_OWNER_NFSV4:
        case STATE_LOCK_OWNER_NFSV4:
        case STATE_CLIENTID_OWNER_NFSV4:
                return ht_nfs4_owner;

This patch puts STATE_LOCK_OWNER_9P under #ifdef _USE_9P back again!
