net: phylink: move test for ovr_an_inband

Of the two users of phylink_config->ovr_an_inband, both manually check
for a fixed link before setting this flag (or clearing it if they find
a fixed link.) This is unnecessary complication.

Test ovr_an_inband before checking for the fixed-link properties, which
will allow ovr_an_inband to be overriden by a fixed link specification.
