[OpenMP] Fixed Bug 49356

[tianshilei1992]

Summary

Bug 49356 (https://bugs.llvm.org/show_bug.cgi?id=49356) reports crash in
the test case tasking/bug_taskwait_detach.cpp, which is caused by the wrong
function declaration. gtid in __kmpc_omp_task should be kmp_int32.

[AndreyChurbanov]

LGTM, with one nit: alias kmp_int64 is never used in the test now, so the declaration can be removed.
