Wang YanQing 20ef288612 ubi: Fix return value overwrite issue in try_write_vid_and_data() ... commit 31a149d5c1 upstream. The commit 2d78aee426 ("UBI: simplify LEB write and atomic LEB change code") adds helper function, try_write_vid_and_data(), to simplify the code, but this helper function has bug, it will return 0 (success) when ubi_io_write_vid_hdr() or the ubi_io_write_data() return error number (-EIO, etc), because the return value of ubi_wl_put_peb() will overwrite the original return value. This issue will cause unexpected data loss issue, because the caller of this function and UBIFS willn't know the data is lost.
