MFC r311305 (by asomers):
Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name)

The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are
fixed-length strings. AFAICT the only place they're read is in
sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated.
However, the kernel doesn't null-terminate them. A bunch of copy-pasted code
uses strncpy to write them, and doesn't guarantee null-termination. For at
least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually
overflows. You can see the result by doing "camcontrol negotiate da0 -v".

This change null-terminates those fields everywhere they're set in the
kernel. It also shortens a few strings to ensure they'll fit within the
16-character field.

ciss(4): Fix overrun of array

The softc member 'ciss_logical' is an array of 'ciss_max_logical_bus' members.
Most of the time it is iterated correctly. This patch fixes the two instances
where the driver iterated off the end of the array.

r249170 was just plain wrong. The effect of the change is to always
delete a logic volume on status change which is NOT what we want here.

The original code is correct in that when the volume changes status
the driver will only delete the volume if the status is one of the
fatal errors. A drive failure in a mirrored volume is NOT a situtation
where the volume should dissapear.
