SYSLINK: ipc - nameserver_get returns properly for nameserver_get_local

nameserver_get_local function has been modified in a recent patch to
return a positive value if it finds a match. The nameserver_get function
internally calls both nameserver_get_local and nameserver_remote_get.
The function is now patched so that it returns properly if the name is present
locally by comparing against a positive value for the return value from
nameserver_get_local, and against zero for nameserver_remote_get.
