Instead of calling __skb_checksum() with a skb_checksum_ops struct that
does CRC32C, just call the new function skb_crc32c().  This is faster
and simpler.

Bernard, since you are the owner and author of the siw driver, please help
with reviewing this patch.

Eric, do you already have a test case for the siw driver? If not,
multiple tests in the blktests framework use this driver intensively,
including the SRP tests that I wrote myself. See also
https://github.com/osandov/blktests.

No.  I'll try that out when I have a chance.

If the developers/maintainers of the driver could help test it, that would be a
lot easier though.  I've been cleaning up the CRC calls across the whole kernel,
and it gets time-consuming when individual subsystems insist on me running their
custom test suite(s) and providing subsystem-specific benchmarks.
