pata_at91: fix ata_host_activate() failure handling
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..."
