[PATCH] x86/mm: Assign the initail value to the pmd_idx

[Minfei Huang <mhuang@redhat.com>]

From: Minfei Huang <mnfhuang@gmail.com>

The variable pmd_idx is undefined, when we try to start the loop to
calculate the page.

Assign the proper value which indexes the start address to make it work
well.
