fs/smartfs: Fix file size corruption when opening with truncate mode

Browse Source 
If a existing file is opened with truncate mode e.g. fopen(file, "w+"),
the file size will be incorrect after writing any data to the file.
Before writing to the first sector, the reading is performed again.
As a result, it makes an invalid file size. When a sector buffer is used,
it must also write to the first sector.
