Is your feature request related to a problem? Please describe.

This is an optimazition of code.

Describe the solution you'd like

The following line of code comes from https://github.com/axios/axios/blob/master/lib/adapters/http.js#L403:

reject(!cancel || (cancel && cancel.type) ? new CanceledError() : cancel);

It can be optimized as follows:

reject(!cancel || cancel.type ? new CanceledError() : cancel);

Describe alternatives you've considered

When the code is executed to (cancel && cancel.type), it means !cancel is false, so cancel is true, we can get cancel.type directly.
