Modified Files:
        src/sys/arch/sparc/dev: zs.c

Log Message:
Establish interrupt handlers with proper softc per each zs device
rather than sharing them among all zs devices and searching softc
in handlers.

The latter method is derived from ancient sun3 zs driver which tried
to reduce overhead on autovectored interrupts, but nowadays such hack
might cause recursive global locks on modern SMP capable framework.

Fixes "5.99.30 sparc panic during startup" reported by Hauke Fath
on tech-kern@:
http://mail-index.NetBSD.org/tech-kern/2010/06/19/msg008374.html
and also tested by Jochen Kunz on SS20 with both serial and kbd console.

Ok'ed by mrg@ and dyoung@.
