Fix the warning: [-Werror=-Wframe-larger-than=]

drivers/net/ethernet/neterion/vxge/vxge-main.c:
In function'VXGE_COMPLETE_VPATH_TX.isra.37':
drivers/net/ethernet/neterion/vxge/vxge-main.c:119:1:
warning: the frame size of 1056 bytes is larger than 1024 bytes

Dropping the NR_SKB_COMPLETED to 16 is appropriate that won't
have much impact on performance and functionality.
