e1000e: fix IPMI traffic

commit eb7c3adb1ca92450870dbb0d347fc986cd5e2af4 upstream.

Some users reported that they have machines with BMCs enabled that cannot
receive IPMI traffic after e1000e is loaded.

This fixes the issue if they load with the new parameter = 0 by disabling
crc stripping, but leaves the performance feature on for most users.
Based on work done by Hong Zhang.
