jbd2: replace __get_free_pages() with kmalloc()

Browse source

jbd2_alloc() falls back from kmem_cache_alloc() to __get_free_pages() for
allocations larger than PAGE_SIZE.
But kmalloc() can handle such cases with essentially the same fallback.

Replace use of __get_free_pages() with kmalloc() and simplify
jbd2_free() as both kmem_cache_alloc() and kmalloc() allocations can be
freed with kfree().
