soc: qcom: geni-se: fix array underflow in geni_se_clk_tbl_get()

Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: geni-se: fix array underflow in geni_se_clk_tbl_get() This loop is supposed to break if the frequency returned from clk_round_rate() is the same as on the previous iteration. However, that check doesn't make sense on the first iteration through the loop. It leads to reading before the start of these->clk_perf_tbl[] array.
