ROMFS: Advance destination buffer pointer when reading from a blockdev
RomFS should advance the destination buffer pointer when reading data from a
blockdev source (the data may be split over multiple blocks, each requiring its
own sb_read() call). Without this, all the data is copied to the beginning of
the output buffer.
