Aneesh Kumar K.V 91246c0090 ext4: Initialize writeback_index to 0 when allocating a new inode ...

The write_cache_pages() function uses the mapping->writeback_index as
the starting index to write out when range_cyclic is set.  Properly
initialize writeback_index so that we start the writeout at index 0.

This was found when debugging the small file fragmentation on ext4.
