[OpenMP] Remove compiler warning about unused value

The compiler warns about an unused variable/statement:

    runtime/src/kmp_affinity.cpp:4958:18: warning: statement has no effect [-Wunused-value]
       KA_TRACE(1000, ; {
                      ^
    runtime/src/kmp_debug.h:84:24: note: in definition of macro 'KA_TRACE'
         __kmp_debug_printf x;                                                      \
                            ^

Instead of the unused reference to this function, this patch now calls the function
with an empty string. The call to this function should have no effect.
