[nvptx] Allow default vl to be overridden in nvptx_goacc_validate_dims_1
In nvptx_goacc_validate_dims_1, allow oacc_default_dims[DIM_VECTOR] to be
overridden, by assigning it to a new variable default_vector_length at the
start, and using it at the end.

* config/nvptx/nvptx.c (nvptx_goacc_validate_dims_1): Add an use new
variable default_vector_length.
