If there is not enough space left, f2fs_preallocate_blocks may only
preallocte partial blocks. As a result, the write operation fails
but i_blocks is not 0. To avoid this, f2fs should write data in
non-preallocation way and write as many data as the size of i_blocks.

This patch introduces a sysfs interface readdir_ra to enable/disable
readaheading inode block in f2fs_readdir. When readdir_ra is enabled,
it improves the performance of "readdir + stat".
For 300,000 files:
time find /data/test > /dev/null
disable readdir_ra: 1m25.69s real 0m01.94s user
Previously, we use free nid list to manage free nid entry, so during nid
allocation, we can just pick up one entry from list header, which has
quite low overhead.
But sadly, during initialization of free nid list, we should do lookup
combining with lots of different inner caches, including NAT pag
alloc_nid_failed and scan_nat_page can be called at the same time,
and we haven't protected add_free_nid and update_free_nid_bitmap
with the same nid_list_lock. That could lead to
