x86: mm: convert ptdump_walk_pgd_level_debugfs() to take an mm_struct

To enable x86 to use the generic walk_page_range() function, the callers
of ptdump_walk_pgd_level_debugfs() need to pass in the mm_struct.

This means that ptdump_walk_pgd_level_core() is now always passed a valid
pgd, so drop the support for pgd==NULL.
