afr: make heal info lockless

Changes in locks xlator:
Added support for per-domain inodelk count requests.
Caller needs to set GLUSTERFS_MULTIPLE_DOM_LK_CNT_REQUESTS key in the
dict and then set each key with name
'GLUSTERFS_INODELK_DOM_PREFIX:<domain name>'.
In the response dict, the xlator will send the per domain count as
values for each of these keys.

Changes in AFR:
Replaced afr_selfheal_locked_inspect() with afr_lockless_inspect(). Logic has
been added to make the latter behave same as the former, thus not
breaking the current heal info output behaviour.
