gpu: nvgpu: unrailgate only if pm_domains not enabled
Currently we unrailgate the GPU if railgating is not enabled
or pm_domains are not enabled
But in case if railgating is not enabled and pm_domains
are enabled, we explicitly unrailgate GPU in gk20a_pm_init()
and then runtime PM unrailgates it again when first user
space request arrives - setting unrailgate refcount to 2
Now for gk20a_do_idle(), we need to railgate the GPU in
fist call but that does not happen since unrailgate
refcount != 1
hence, in case railgating is not enabled, we should
unrailgate the GPU from only one place i.e. when first user
space request arrives
