perf list: Fix the --no-desc option

perf list: Fix the --no-desc option

Currently, the --no-desc option in perf list isn't functioning as
intended.

This issue arises from the overwriting of struct option->desc with the
opposite value of struct option->long_desc. Consequently, whatever
parse_options() returns at struct option->desc gets overridden later,
rendering the --desc or --no-desc arguments ineffective.

To resolve this, set ->desc as true by default and allow parse_options()
to adjust it accordingly. This adjustment will fix the --no-desc
option while preserving the functionality of the other parameters.
