x86/oops: Show the correct CS value in show_regs()
show_regs() shows the CS in the CPU register instead of the value in
regs. This means that we'll probably print "CS: 0010" almost all
the time regardless of what was actually in CS when the kernel
malfunctioned. This gives a particularly confusing result if we
OOPSed due to an implicit supervisor access from user mode.
