Jaegeuk Kim dc91de78e5 f2fs: do not preallocate blocks which has wrong buffer
Sheng Yong reports needless preallocation if write(small_buffer, large_size)
is called.

In that case, f2fs preallocates large_size, but vfs returns early due to
small_buffer size. Let's detect it before preallocation phase in f2fs.
