Avoid enqueueing the same event multiple times in nbnxn_atomdata_x_to_nbat_x_gpu

With several non-local grids, we were calling
nbnxnInsertNonlocalGpuDependency(nb, NonLocal) in nbnxn_gpu_x_to_nbat_x
after enqueueing the transformation kernel for each one.

Now, we only call it once after submitting all kernels for
given locality (marking the event for Local, enqueueing the wait for it
for NonLocal).

Refs #3988.
