tty: serial: qcom-geni-serial: Fix %lu -> %u in print statements

When we multiply an unsigned int by a u32 we still end up with an
unsigned int. That means we should specify "%u" not "%lu" in the
format code.

NOTE: this fix was chosen instead of somehow promoting the value to
"unsigned long" since the max baud rate from the earlier call to
uart_get_baud_rate() is 4000000 and the max sampling rate is 32.
4000000 * 32 = 0x07a12000, not even close to overflowing 32-bits.

Fixes: c474c77571 ("tty: serial: qcom-geni-serial: Fix get_clk_div_rate() which otherwise could return a sub-optimal clock rate.")
