[PATCH] Fix check_partition routines

check_partition() stops its probe once it hits an I/O error from the
partition checkers.  This would prevent the actual partition checker
getting a chance to verify the partition.

So this patch lets check_partition() continue probing untill it hits a
success while recording the I/O error which might have been reported by the
checking routines.

Also, it does some cleanup of the partition methods for ibm, atari and
amiga to return -1 upon hitting an I/O error.
