Modified Files:
        src/sys/dev/scsipi: scsipi_ioctl.c
        src/sys/kern: kern_physio.c

Log Message:
fix ioctl problems after the recent physio changes
in some drivers including wd and scsi.

- physio: if a caller provided a buf, stick to use it
  because some drivers use it as an identifier.
- sprinkle simple_locks.
- scsistrategy: rather than issueing an async request and
  waiting for its completion, simply issue a sync request.
  the way to wait for the completion had an assumption that
  B_CALL is never used.  it isn't the case after the recent
  physio() changes.
