Arguments passed into WEXITSTATUS() should have been initialized earlier. Otherwise following warning show up while building platform selftests on arm64. Hence just zero out all the relevant local variables to avoid the build warning.

Warning: ‘status’ may be used uninitialized in this function [-Wmaybe-uninitialized]
