[PATCH] tools/power turbostat: fix overflow read on array slm_freq_table

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

When i >= SLM_BCLK_FREQS, the frequency read from the slm_freq_table
is off the end of the array because msr is set to 3 rather than the
actual array index i.  Set i to 3 rather than msr to fix this.
