[patch] cfi: remove warning message on expected behaivor

["Jan Pedersen" <jan.pedersen@glaze.dk>]

When an erase operation is in progress, the DQ5 (data bit 5 / exceeded
timing limit) pin on the flash chips may raise just before operation
complete is detected. This is expected behaivor because when the erase is
complete, DQ5 switches from 'exceeded timing limit' to 'data bit 5' which
therefore might be read as '1' just before operation complete is detected.
This fix is well tested.
