Subject: [PATCH 4.19 186/323] soc/tegra: Fix an error handling path in tegra_powergate_power_up()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 986b5094708e508baa452a23ffe809870934a7df ]

If an error occurs after a successful tegra_powergate_enable_clocks()
call, it must be undone by a tegra_powergate_disable_clocks() call, as
already done in the below and above error handling paths of this function.

Update the 'goto' to branch at the correct place of the error handling
path.

Fixes: a38045121bf4 ("soc/tegra: pmc: Add generic PM domain support")
