ieee1394: remove unused variables

which caused gcc 4.6 to warn about
    variable 'XYZ' set but not used.

sbp2.c, unit_characteristics:

The underlying problem which was spotted here --- an incomplete
implementation --- is already 50% fixed in drivers/firewire/sbp2.c which
observes mgt_ORB_timeout but not yet ORB_size.

raw1394.c, length_conflict; dv1394.c, ts_off:

Impossible to tell why these variables are there.  We can safely remove
them though because we don't need a compiler warning to realize that we
are dealing with (at least stylistically) flawed code here.

dv1394.c, packet_time:

This was used in debug macro that is only compiled in with
DV1394_DEBUG_LEVEL >= 2 defined at compile-time.  Just drop it since
nobody debugs dv1394 anymore.  Avoids noise in regular kernel builds.

dv1394.c, ohci; eth1394.c, priv:

These variables clearly can go away.  Somebody wanted to use them but
then didn't (or not anymore).

Note, all of this code is considered to be at its end of life and is
thus not really meant to receive janitorial updates anymore.  But if we
can easily remove noisy warnings from kernel builds, we should.
