serial: imx: fix error handling in console_setup
[ Upstream commit 63fd4b94b948c14eeb27a3bbf50ea0f7f0593bad ]
The ipg clock only needs to be unprepared in case preparing
per clock fails. The ipg clock has already disabled at the point.
Fixes: 1cf93e0d5488 ("serial: imx: remove the uart_console() check")
