Subject: [PATCH] x86/mm: Initialize pmd_idx in page_table_range_init_count()

The variable pmd_idx is not initialized for the first iteration of the
for loop.

Assign the proper value which indexes the start address.

Fixes: 719272c45b82 'x86, mm: only call early_ioremap_page_table_range_init() once'
