Initialize two variables in kmp_tasking.
Summary:
Two initialized local variables are causing clang to produce warnings:
```
./src/projects/openmp/runtime/src/kmp_tasking.c:3019:5: error: variable 'num_tasks' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
default:
^~~~~~~
./src/projects/openmp/runtime/src/kmp_tasking.c:3027:21: note: uninitialized use occurs here
for( i = 0; i < num_tasks; ++i ) {
^~~~~~~~~
./src/projects/openmp/runtime/src/kmp_tasking.c:2968:28: note: initialize the variable 'num_tasks' to silence this warning
kmp_uint64 i, num_tasks, extras;
^

2 errors generated.
```
This patch initializes these two variables.
