serial: 8250_bcm2835aux: Add missing clk_disable_unprepare()
The error path when get clock frequency fails in bcm2835aux_serial
driver does not correctly disable the clock.
This flaw was found using a static analysis tool "Hulk Robot", which
reported the following warning when analyzing linux-next/master:
drivers/tty/serial/8250/8250_bcm2835aux.c:
warning: clk_disable_unprepare_missing.cocci
The cocci script checks for the existence of clk_disable_unprepare()
paired with clk_prepare_enable().
Add the missing clk_disable_unprepare() to the error path.
