vmxnet3: reduce calling vmxnet3_reg_write_inline
In output.c, we buffer the descriptors and call vmxnet3_reg_write_inline
once outside the loop. This change improves the performance dramatically.
When refilling the ring, there is no need to inform the device unless
explicitly specified by the device (ctrl.update_prod == 1)
