[OpenMP-RT] Fix debug string for NVPTX runtime library

[carlo.bertolli]

Summary

The method ThreadsInTeam is used to determine the number of threads to be used in a parallel region under SPMD mode (see line 127 of supporti.h in libomptarget/deviceRTLs/nvptx/src/). This patch fixes the corresponding debug print upon initialization of the kernel in SPMD mode.

[Hahnfeld]

Right, nthreads should be zero if I read InitLevelOneTaskDescr correctly?

[carlo.bertolli]

That's correct, debug printfs were reporting zero threads to be used in SPMD region instead of the actual number used.

Committed revision 323978.
