7f47d8cc ("x86, tracing, perf: Add trace point for MSR accesses") added tracing of msr read and write, but because of complexity in having tracepoints in headers, and even more so for a core header like msr.h, not to mention the bloat a tracepoint adds to inline functions, a helper function is needed to be called from the header. Use the new tracepoint_enabled() macro in tracepoint-defs.h to test if the tracepoint is active before calling the helper function, instead of open coding the same logic, which requires knowing the internals of a tracepoint.
