f2fs: avoid sleeping under spin_lock
In the call trace below, we might sleep in function dput().
So in order to avoid sleeping under spin_lock, we remove f2fs_mark_inode_dirty_sync
from __try_update_largest_extent && __drop_largest_extent.
BUG: sleeping function called from invalid context at fs/dcache.c:796
