Subject: x86/mm: Initialize pmd_idx in page_table_range_init_count()

From: Minfei Huang <[email protected]>

commit 9962eea9e55f797f05f20ba6448929cab2a9f018 upstream.

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

Assign the proper value which indexes the start address.
