raid5: remove gfp flags from scribble_alloc()
Using GFP_NOIO flag to call scribble_alloc() from resize_chunk() does not have the expected behavior. kvmalloc_array() inside scribble_alloc() which receives the GFP_NOIO flag will eventually call kmalloc_node() to allocate physically continuous pages. Now we have memalloc scope APIs in mddev_suspend()/mddev_resume() to prevent memory reclaim I/Os during raid array suspend context, calling to kvmalloc_array() with GFP_KERNEL flag may avoid deadlock of recursive I/O as expected. This patch removes the useless gfp flags from parameters list of scribble_alloc(), and call kvmalloc_array() with GFP_KERNEL flag. The incorrect GFP_NOIO flag does not exist anymore.
