[PATCH net-next] net: neterion: Remove set but not used variable

[Zheng Yongjun]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/neterion/vxge/vxge-traffic.c: In function 
vxge_hw_vpath_intr_disable:
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:160:6: warning: variable 
‘val64’ set but not used [-Wunused-but-set-variable]

drivers/net/ethernet/neterion/vxge/vxge-traffic.c: In function 
vxge_hw_vpath_intr_enable:
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:33:6: warning: variable 
‘val64’ set but not used [-Wunused-but-set-variable]

drivers/net/ethernet/neterion/vxge/vxge-traffic.c: In function 
vxge_hw_device_flush_io:
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:490:6: warning: variable 
‘val32’ set but not used [-Wunused-but-set-variable]

drivers/net/ethernet/neterion/vxge/vxge-traffic.c: In function 
vxge_hw_vpath_poll_rx:
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:2378:6: warning: variable 
‘val64’ set but not used [-Wunused-but-set-variable]

these variable is never used, so remove it.
