Summary
smb: server: fix leak of active_num_conn in ksmbd_tcp_new_connection()
Details

In the Linux kernel, the following vulnerability has been resolved:

smb: server: fix leak of activenumconn in ksmbdtcpnew_connection()

On kthreadrun() failure in ksmbdtcpnewconnection(), the transport is freed via freetransport(), which does not decrement activenum_conn, leaking this counter.

Replace freetransport() with ksmbdtcp_disconnect().
