x86: Make sure we also print a Code: line for show_regs()



show_regs() is called as a mini BUG() equivalent in some places,
specifically for the "scheduling while atomic" case.

Unfortunately right now it does not print a Code: line unlike
a real bug/oops.

This patch changes the x86 implementation of show_regs() so that
it calls the same function as oopses do to print the registers
as well as the Code: line.
