serial: lpuart: Return value from correct variable
In get_lpuart_clk_rate if the call to clk_get_rate returns an error then
the call to return should pass the value of the error which is in rate
rather than ret which will be 0 as its value is not affected by this
error.
This issue was found by Smatch.
