happy-eyeballs: Reserve array length for all candidates

Browse Source 
The code currently assumes that the array does not change during
execution, this assumption is violated when the darray resizes causing
previous pointers to point to invalid memory and cause undefined
behavior and crashes.

This may need refactoring in the future, this commit simply fixes the
issue for now.
