drivers/net/ethernet/amd/pcnet32.c: neaten and remove unnecessary OOM messages 

Make the code flow a little better for 80 columns.

Use a consistent style for the RX and TX rings allocation.
Use BIT macro.
Use a temporary unsiged int entries for (1<<size).
Remove the OOM messages as they duplicate the generic
OOM and dump_stack() provided by the memory subsystem.
Reflow allocs to 80 columns.
