LE Manh Cuong 56d357773e singleflight: fix duplicate deleting key when Forget called 
When Forget was called, we delete key associated with current call from
map. When that call is done, it does delete key again, causing the same
key set by other call after Forget lost.

To fix it, adding a boolean value to check whether the call is forgotten,
the call only does delete key if Forget is not called.

Fixes golang/go#31420
