do not reuse connection if share marked as isolated
"SHAREFLAG_ISOLATED_TRANSPORT" indicates that we should not reuse the socket for this share (for future mounts). Mark the socket as server->nosharesock if share flags returned include SHAREFLAG_ISOLATED_TRANSPORT. See MS-SMB2 MS-SMB2 2.2.10 and 3.2.5.5 Signed-off-by: Steve French <stfrench@microsoft.com>
