nvptx: remove erroneous stack deletion

The stacks are not supposed to be deleted every time memory is allocated, only
when there is insufficient memory.  The unconditional call here seems to be in
error, and is causing a costly reallocation of the stacks before every launch.

	* plugin/plugin-nvptx.c (GOMP_OFFLOAD_alloc): Remove early call to
	nvptx_stacks_free.
