[U-Boot] [PATCH] fs: ext4: Prevent erasing buffer past file size

The variable 'n' represents the number of bytes to be read from a certain offset in a file, to a certain offset in buffer 'buf'. The variable 'len' represents the length of the entire file, clamped correctly to avoid any overflows. Therefore, comparing 'n' and 'len' to determine whether clearing '
