In the alignment check added to qemu_ram_alloc_from_fd() in commit ce317be98db0dfdfa, the condition includes a check that 'mr' is not NULL. This check is unnecessary because we can assume that the caller always passes us a valid MemoryRegion, and indeed later in the function we assume mr is not NULL when we pass it to file_ram_alloc() as new_block->mr. Remove it.
