[PATCH] PCI: imx6: fix pwrctrl device leak on PM runtime setup failure

[hanzhijian]

In imx_pcie_probe(), after pci_pwrctrl_create_devices() creates the
pwrctrl devices, the error paths for imx_add_pcie_ep() and
dw_pcie_host_init() both jump to err_pwrctrl_destroy to tear them down.
However, the error path for devm_pm_runtime_set_active_enabled() returns
directly, leaking the pwrctrl devices.

Jump to err_pwrctrl_destroy instead so the pwrctrl devices are cleaned
up on this error path too.
