serial: msm-geni: Detect error from get_clk_div_rate

In msm_serial_setbrg if the call to get_clk_div_rate fails then there
will not have been an assignment to clk_div which will lead to the call
to geni_serial_baud using an uninitialised value.
Check for an error from get_clk_div_rate and return an error code if so.
