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
