Documentation: admin-guide: cpufreq: fix sampling_rate example command
The example shell command for setting ondemand's sampling_rate wraps an
arithmetic expansion $((...)) in command-substitution backticks. The
arithmetic result is then executed as a command, which fails and writes
an empty value. Drop the surrounding backticks so the computed value is
passed to echo as intended.
