pcnet_cs: Use pr_fmt and pr_<level>

It looks as if the printks in get_ax88190 are
incorrect and were duplicated and superceded by a
test in pcnet_config, so I removed them.

Changed the level of the ax88190 test to KERN_NOTICE
to match the other message styles in pcnet_config.

Compiled but untested.
