drivers: net: davinci_cpdma: remove CRC bytes from skb added by CPDMA

Additional 4 bytes found in the skb is the CRC calculated by the
CPDMA hardware, check the CRC bit in CPDMA status field of
Descriptor and remove the CRC length from the skb. This extra
4 byte can be seen when capturing packets using tcpdump.
This has been tested in TI816x platform.
