Subject: [PATCH net-next] net: neterion: vxge: remove set but not used variables 'max_frags' and 'txdl_priv'

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

drivers/net/ethernet/neterion/vxge/vxge-traffic.c:1698:35:
 warning: variable 'txdl_priv' set but not used [-Wunused-but-set-variable]
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:1699:6:
 warning: variable 'max_frags' set but not used [-Wunused-but-set-variable]

It never used since introduction in
commit 113241321dcd ("Neterion: New driver: Traffic & alarm handler")
