Fix bug #7617 - smbd coredump due to uninitialized variables in the performance counter code.
In the file rpc_server.c, function _winreg_QueryValue()
uint8_t *outbuf
Should be :
uint8_t *outbuf = NULL;
As it is later freed by
if (free_buf) SAFE_FREE(outbuf);
in some cases, this frees the unintialized outbuf, which causes a coredump.
