Ensure we don't re-issue a failed buf without clearing B_ERROR and

b_error. Otherwise a good i/o will appear to have failed. Fixes
problem with dkcsum.c being unable to read data to checksum from
subsequent devices after an i/o fails. And thus failing to find
correct root in some cases.

Introduced at k2k11 with buf flags rectification. Scan of all
biowait() calls finds no other obvious re-use of a buf that could
have error'ed out. Just re-use of bufs that worked. So quick fix
pending closer review of all uses.

Problem noted by Jens A. Griepen.
