4.1c sh "not found" errors

[Bill Shannon]

I'm sure I responded to this before but perhaps my response was lost.
The bug is in ufs_bio.c in (I think) biodone().  My previous response
gave the exact fix but I'm too lazy to dig it out a second time.  I
think the problem is that biodone does

	u.u_error = geterror();

where it should do

	if (u.u_error == 0)
		u.u_error = geterror();
