pata_at91: fix ata_host_activate() failure handling

commit 27aa64b9d1bd0d23fd692c91763a48309b694311 upstream.

Add missing clk_put() call to ata_host_activate() failure path.

Sergei says,

  "Hm, I have once fixed that (see that *if* (!ret)) but looks like a
   later commit 477c87e9 (ARM:
   at91/pata: use gpio_is_valid to check the gpio) broke it again. :-(
   Would be good if the changelog did mention that..."
