Subject: x86: Fix VMI for early params...for mainline

While fixing a recent breakage in VMI on the recent x86 tree, I noticed
that vmi specific kernel commandline parameters were broken. Below is
the fix.

Please note this needs to go into the mainline tree.

x86: Fix VMI for early params

From: Alok N Kataria <[email protected]>

In a recent commit 31343d8a5079cda57ffd539fcf4f00cea344fe98,
while fixing a different bug, I moved the call to vmi_init before
early params could be parsed.
This broke the vmi specific commandline parameters.
Fix that, by moving vmi initialization after kernel has got a chance to
parse early parameters.
