x86/msr: Harmonize the prototype and definition of do_trace_rdpmc()

In <asm/msr.h> the first parameter of do_trace_rdpmc() is named 'msr':

extern void do_trace_rdpmc(unsigned int msr, u64 val, int failed);

But in the definition it's 'counter':

void do_trace_rdpmc(unsigned counter, u64 val, int failed)

Use 'msr' in both cases, and change the type to u32.
