netxen: fix warnings

drivers/net/netxen/netxen_nic_hw.c: In function 'netxen_nic_hw_resources':
drivers/net/netxen/netxen_nic_hw.c:231: warning: format '%llx' expects type 'long long unsigned int', but argument 2 has type 'dma_addr_t'
drivers/net/netxen/netxen_nic_hw.c:250: warning: format '%llx' expects type 'long long unsigned int', but argument 2 has type 'dma_addr_t'

u64 is unsigned long so the cast to u64 will result in a warning on the
printf arguments for 64-bit builds.  So cast to unsigned long long instead.
