so don't need to set bl_len to ask spl_load_simple_fit to handle

Actually spl_load_simple_fit has two parts of reading:
spl_simple_fit_read and spl_load_fit_image.
The spl_load_fit_image can handle the page unaligned offset,
but the spl_simple_fit_read can't do it. spl_simple_fit_read requires
the FIT location at page aligned offset.
