daemon: reloadMaxDownloadAttempts() remove validation

Browse source 
reloadMaxDownloadAttempts() is used to reload the configuration,
but validation happened before merging the config with the defaults.

This removes the validation from this function, instead centralizing
validation in config.Validate().

NOTE:
Currently this validation is "ok", as it checks for "nil" values;
I am working on changes to reduce the use of pointers in the config,
and instead provide a mechanism to fill in defaults. This change is
in preparation of that.
