 leon,grspw: fix for SET_PACKET_SIZE

 When the DMA table has been allocated dynamically, the
 IOCTL_SET_PACKETSIZE
 will trigger an issue where pDev->rx and pDev->tx are not updated with
 the new DMA tables base address. Instead the old pointers are used.

 There is no point in reallocting the DMA tables because there is no
 configuration option to it. Therefore the DMA tables allocation is
 moved to a separate function never called from SET_PACKETSIZE.

 Update #4304.
