net: fix improper Context.Deadline usage in DialContext

The existing implementation is erroneously assume that having no
deadline in context.Context means that time returned from Deadline
method will have IsZero() == true. But technically speaking this is an
invalid assumption. The context.Context interface specification doesn't
specify what time should be returned from Deadline method when there is
no deadline set. It only specifies that second result of Deadline should
be false.

Fixes #35594
