corey-derochie-amd 17becdb7f8 [SWDEV-497665] Blocked cudaMemcpyAsync race condition by synchronizing (#1447) ...

* Switched calls to `cudaMemcpyAsync` to be `cudaMemcpy` in `ncclTransportP2pSetup` to avoid race condition with `cudaIpcOpenMemHandle` inside p2p `connect`. See `ncclP2pImportShareableBuffer`.

* Moved synchronize outside of the loop, as it isn't necessary to sync between every iteration of the loop.
