null_blk: remove hardcoded null_alloc_page() param
Only caller of null_alloc_page() is null_insert_page() unconditionally sets only parameter to GFP_NOIO and that is statically hard-coded in null_blk. There is no point in having statically hardcoded function parameter. Remove the unnecessary parameter gfp_flags and adjust the code, so it can retain existing behavior null_alloc_page() with GFP_NOIO.
