perf_counter: include missing header

Impact: build fix

In order to compile a kernel with performance counter patches,
<asm/irq_regs.h> has to be included to provide the declaration of
struct pt_regs *get_irq_regs(void);

[ This bug was masked by unrelated x86 header file changes in the
x86 tree, but occurs in the tip:perfcounters/core standalone
tree. ]
