Suppress Thread Sanitizer for Accept and Disconnect

Browse Source 
Thread Sanitizer reports two data races on CancelAccept and
CallingThread in SOCK, shared between Accept(Accept6) and Disconnect.
These are used when interrupting an Accept operation from a Disconnect.
These races are benign because they work correctly even if both fields
have old values.
