sky2: Fix checksum endianness
[ Upstream commit b9389796fa4c87fbdff33816e317cdae5f36dd0b ]
sky2 driver on PowerPC targets floods kernel log with following errors:
eth1: hw csum failure.
Call Trace:

The NIC is Yukon-2 EC chip revision 1.
Converting checksum field from le16 to CPU byte order fixes the issue.
