Revert "e1000: fix sw fw sync on igb i210/i211"

This reverts commit 17da712024.

The i210/i211 do have the SW_FW_SYNC (0x5b5c) register and this is what should
be used when acquiring the semaphore.

I believe the issue that this patch was trying to resolve is now resolved
by properly releasing the semaphore once no longer needed.
