ext4: kunit: use dynamic inode allocation

Storing an inode structure on the stack pushes some functions over the warning
limit for stack frame size:

In file included from fs/ext4/mballoc.c:7039:
fs/ext4/mballoc-test.c:506:13: error: stack frame size (1032) exceeds limit (1024) in 'test_mark_diskspace_used' [-Werror,-Wframe-larger-than]
  506 | static void test_mark_diskspace_used(struct kunit *test)
      |             ^

Use kunit_kzalloc() for all inodes. There may be a better way to do it by
preallocating the inode, which would result in a larger rework.
