ARM: 9244/1: dump: Fix wrong pg_level in walk_pmd()

Browse Source 
[ Upstream commit 2ccd19b3ffac07cc7e75a2bd1ed779728bb67197 ]

After ARM supports p4d page tables, the pg_level for note_page()
in walk_pmd() should be 4, not 3, fix it.

Fixes: 84e6ffb2c4 ("arm: add support for folded p4d page tables")
