e1000e: 82579 jumbo frame workaround causing CRC errors

The subject workaround was causing CRC errors due to writing the wrong
register with updates of the RCTL register.  It was also found that the
workaround function which modifies the RCTL register was being called in
the middle of a read-modify-write operation of the RCTL register, so the
function call has been moved appropriately.  Lastly, jumbo frames must not
be allowed when CRC stripping is disabled by a module parameter because the
workaround requires the CRC be stripped.
