Joe Perches 60b8675592 usbnet: Convert dev(dbg|err|warn|info) macros to netdev_<level> 
These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

Fix net1080 this/other log message inversion.
