Revert "arm64/mm: Drop redundant BUG_ON(!pgtable_alloc)"

Browse source

This reverts commit 9ed2b4616d.

Nathan reports early boot failures bisected to this change which look
related to the kPTI nG repainting. In any case, consolidating the
BUG_ON()s to a single location needs more thought, so revert the change
until this is figured out properly.
