clocksource/drivers/timer-econet-en751221: Fix clock reference leak
timer_init() obtains the timer clock with of_clk_get() and only reads
its frequency with clk_get_rate(); the clock is never prepared nor
enabled. All four return paths after the acquisition (of_iomap()
failure, clocksource_mmio_init() failure, cevt_init() failure and
success) return without clk_put(), leaking the consumer reference.
Drop the reference with clk_put() right after the frequency has been
read. The clock enable state is untouched.
