perf/x86/intel/uncore: Remove extra double quote mark
The third argument in INTEL_UNCORE_FR_EVENT_DESC() is subject to
__stringify(), and the extra double quote marks can result in the
expansion "3.814697266e-6" in the sysfs knobs, instead of
3.814697266e-6.
This is incorrect, though it may still work for perf, e.g.
perf stat -e uncore_iio_free_running_0/bw_in_port0/
Fixes: d8987048f665 ("perf/x86/intel/uncore: Support IIO free-running counters on DMR")
Closes: https://lore.kernel.org/all/20251231224233.113839-1-zide.chen@intel.com/
