[PATCH] xtensa: time: Fix clk reference leak in calibrate_ccount()

[blaze]

In calibrate_ccount(), of_clk_get() acquires a reference to the CPU clock,
but clk_put() is never called to release it. The clock reference is used
only to read the frequency via clk_get_rate(), then the function returns
immediately, leaking the reference.

Fix this by calling clk_put(clk) before returning.
