Palmer Dabbelt f2913d006f RISC-V: Avoid dereferening NULL regs in die() ...

I don't think we can actually die() without a regs pointer, but the
compiler was warning about a NULL check after a dereference.  It seems
prudent to just avoid the possibly-NULL dereference, given that when
die()ing the system is already toast so who knows how we got there.
