Modified Files:
	syssrc/sys/dev/scsipi: st.c

Log Message:
* st_touch_tape(): start probing at the block size from the sense data if
  we have it.

* st_unmount(): reset density to the device default. This prevents using
  stale density values after changing to a medium with different density.

  Section 9.3.3 of the SCSI specs states that a device shall return the
  density value specified in the last succesfull MODE SELECT after an
  unload operation, in case it is not able to automatically determine
  the density of the new medium.
