Yi Yang 38f28cfe9d serial: tegra: Add missing clk_disable_unprepare() in tegra_uart_hw_init() ...

Add the missing clk_disable_unprepare() before return from
tegra_uart_hw_init() in the error handling path.
When request_irq() fails in tegra_uart_startup(), 'tup->uart_clk'
has been enabled, fix it by adding clk_disable_unprepare().

Fixes: cc9ca4d958 ("serial: tegra: Only print FIFO error message when an error occurs")
Fixes: d781ec21ba ("serial: tegra: report clk rate errors")
