e1000e: swap max hw supported frame size between 82574 and 82583

commit a825e00c98a2ee37eb2a0ad93b352e79d2bc1593 upstream.

There appears to have been a mixup in the max supported jumbo frame size
between 82574 and 82583 which ended up disabling jumbo frames on the 82574
as a result.  This patch swaps the two so that this issue is resolved.

This patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=14261
