__create_pgd_mapping_locked() expects a page allocator used while mapping a virtual range. This page allocator function propagates down the call chain, while building intermediate levels in the page table. Passed page allocator is a necessary ingredient required to build the page table but its presence can be asserted just once in the very beginning rather than in all the down stream functions. This consolidates BUG_ON(!pgtable_alloc) checks just in a single place i.e __create_pgd_mapping_locked().
