  Finer grained error records for provider load/init failures

When a provider is activated, these three cases would record that the
provider init function failed (implying that it was called):

-   failure to load the provider module (in case it's a dynamically
    loadable module)
-   the init function not being present (i.e. being NULL)
-   the init function being called and returning an error indication
    (i.e. returning a false value)

This is confusing.

Separating the three cases so that they record different errors will
make it easier to determine causes of failure.
