Bug in panic() in sys/prf.c

[utzoo!decvax!ucbvax!ihnss!houxi!vax135!harpo!utah-cs!lepreau]

	Unless I'm missing something very obvious, the exprs are backwards
	in the conditional statement which determines whether or not this
	is the second call to panic (in order to avoid the sync).  Thus a
	sync is never done in "normal" panics.  [Not sure that's such a bad
	thing though!]

To reproduce:
	Known from code perusal only.

Know fix:
1c1
< /*	prf.c	4.18	81/06/11	*/
---
> /*	prf.c	4.18.1   82/02/18	*/
173c173
< 	int bootopt = panicstr ? RB_AUTOBOOT : RB_AUTOBOOT|RB_NOSYNC;
---
> 	int bootopt = panicstr ? RB_AUTOBOOT|RB_NOSYNC : RB_AUTOBOOT;
