Most errors that can occur in sja1105_static_config_reload() are fatal
(example: fail to communicate with hardware), but not all are.
For example, sja1105_static_config_upload() -> kcalloc() may fail, and
if that happens, we have called phylink_replay_link_begin() but never
phylink_replay_link_end().
Under that circumstance, all port phylink instances are left in a state
where the resolver is stopped with the PHYLINK_DISABLE_REPLAY bit set.
We have effectively disabled link management with no way to recover from
this condition.
Avoid that situation by ensuring phylink_replay_link_begin() is always
paired with phylink_replay_link_end(), regardless of whether we faced
any errors during switch reset, configuration reload and general state
reload.
