auth: return early in LoginRequired on API key validation

Simplify the logic in the LoginRequired decorator when Kallithea is accessed
using an API key. Either:
- the key is valid and API access is allowed for the accessed method
(continue), or
- the key is invalid (redirect to login page), or
- the accessed method does not allow API access (403 Forbidden)

In none of these cases does it make sense to continue checking for user
authentication, so return early.
