[PATCH] 8139x: reduce message severity on driver overlap

[PATCH] 8139x: reduce message severity on driver overlap

[Stephen Hemminger]

The 8139 drivers are a source of error messages that confuse users.
Since this device can not be disambiguated by normal PCI device id's two drivers
match the same info. But the module utilities seem to correctly handle this overlap,
they try one driver, then if that doesn't load try the other. Therefore there is
no need for a message to be logged with error level severity, just using info
level instead. Can't be completely silent because user might have configure one driver
and forgot the other one.
