target-arm: Reindent ancient page-table-walk code

Browse source 
A few of the oldest parts of the page-table-walk code have broken indent
(either hardcoded tabs or two-spaces). Reindent these sections.

For ease of review, this patch does not touch the brace style and
so is a whitespace-only change.

Backports commit 554b0b09aec4579c8164f363b18a263150e91a2c from qemu
