	with inode resize

Hi,

I tested this series with the following usecase:

  a) using mkfs create a badblock map and see if the inode resize fail if
     it find a mapping blocks as bad block.
  b) On resizing inode if we find the mapping block having block bitmap
    or inode bitmap we make sure we find a block in the same group. Used
    debugfs set_bg to force a block bitmap after inode table.
  c) If not we fail the inode resize
  d) If we don't have enough space left we fail inode resize.
