Add missing arcstats

Browse Source 
The following useful values were missing the arcstats.  This change
adds them in to provide greater visibility in to the arcs behavior.

arc_no_grow                     4    0
arc_tempreserve                 4    0
arc_loaned_bytes                4    0
arc_meta_used                   4    624774592
arc_meta_limit                  4    400785408
arc_meta_max                    4    625594176
