x86/vector: Remove the macro VECTOR_OFFSET_START

Now, Linux uses matrix allocator for vector assignment, the original
assignment code which used VECTOR_OFFSET_START has been removed.

So remove the stale macro as well.

Fixes: commit 69cde0004a4b ("x86/vector: Use matrix allocator for vector assignment")
