f2fs: still write data if preallocate only partial blocks

Browse source

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.
