net.lua - No callback on connection errors

[d4rkmen]

When its connection error happened and it should call the callback with error message, it just closes the handle silently

Here it should pass the callback to destroy():

luvit/deps/net.lua

Line 228 in a8c708e

return self:destroy(err)

And here is should pass the exception to the callback

luvit/deps/net.lua

Line 262 in a8c708e

callback()
