Revert "x86/UV: Add uvtrace support"
This reverts commit 8eba18428ac926f436064ac281e76d36d51bd631. uv_trace() is not used by anything, nor is uv_trace_nmi_func, nor uv_trace_func. That's not how we do instrumentation code in the kernel: we add tracepoints, printk()s, etc. so that everyone not just those with magic kernel modules can debug a system. So remove this unused (and misguied) piece of code.
