arch, net: remove the last csum_partial_copy() leftovers
Most of the tree only uses and implements csum_partial_copy_nocheck, but the c6x and lib/checksum.c implement a csum_partial_copy that isn't used anywere except to define csum_partial_copy. Get rid of this pointless alias. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S. Miller <davem@davemloft.net>
