This reverts commit 39fe2fc96694164723846fccf6caa42c3aee6ec4. Parameter extra_mem_pages in vm_create_default() is used to calculate the page table size for all the memory chunks. Real memory allocation for non-slot0 memory happens by extra call of vm_userspace_mem_region_add() outside of vm_create_default(). The reverted commit changed above meaning of extra_mem_pages as extra slot0 memory size. This way made the page table size calculations open coded in separate test.
