Fix compile errors in altera_sdcard_io.c after r357647
Summary:
After rS357647, building universe results in compilation errors for
_.mips.BERI_DE4_SDROOT:

sc->as_currentbio = *bp;
^The first few are because -> has a higher precedence than *, so the
expressions should use (*bp)->foo instead. I also renamed the
variable to bpp to make it clearer that it is a pointer-to-pointer.
The last one is because sc->as_currentbio is already a struct bio *,
there is no need to dereference bp there.
Last but not least, I would really suggest rewriting the
altera_sdcard_io_start_internal() function to just return success or
failure, so the caller can decide to set bp to NULL.
