NetXen: Fix compile failure seen on PPC architecture

NetXen: Add NETXEN prefixes to macros to clean them up.
This is a cleanup patch which adds NETXEN prefix to some stand
alone macro names.
These posed compile errors when NetXen driver was backported to 2.6.9
on PPC architecture as macros like USER_START are defined in file
arch/ppc64/mm/hash_utils.c
