#202 API saLckResourceOpen returns zero during controller failover

[Hrishikesh]

Changeset : 4241 with 2794&3117 patch
Transport : TCP/ipv6-linklocal
PBE enabled.

Scenario:
During Controller failover the below scenario was ran.
Intialize an application with Lock Service using saLckInitialize(). Call saLckResourceOpenAsync() and saLckResourceLockAsync() with valid parameters.
But saLckResourceOpen returns "0" (zero) an invalid return value.
