ixgbe: fix 82598 SFP initialization after driver load.
If we loaded the driver with out a SFP module plugged in it would
leave it in a state that make it later unable to link when a module
was plugged in. This patch corrects that by:
ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from
after get_invariants() to after reset_hw() as now reset_hw() is
where this condition will be indentified.
ixgbe_reset_hw_82598() - Enable this function to now return
IXGBE_ERR_SFP_NOT_PRESENT.
ixgbe_identify_sfp_module_generic() - This where the lack of SFP
module is detected. Modifications are added to allow a different
return value for modules that just haven't been plugged in yet.
Other functions were updated to allow correct logging.
