pinctrl: pinconf-generic: Fix memory leak in pinconf_generic_parse_dt_config()

[ Upstream commit 7a648d598cb8e8c62af3f0e020a25820a3f3a9a7 ]

In pinconf_generic_parse_dt_config(), if parse_dt_cfg() fails, it returns
directly. This bypasses the cleanup logic and results in a memory leak of
the cfg buffer.

Fix this by jumping to the out label on failure, ensuring kfree(cfg) is
called before returning.
