soc: ti: omap-prm: Do not check rstst bit on deassert if already deasserted

[ Upstream commit c1995e5afaf6abf3922b5395ad1f4096951e3276 ]

If a rstctrl reset bit is already deasserted, we can just bail out early
not wait for rstst to clear. Otherwise we can have deassert fail for
already deasserted resets.
