ASoC: topology: Fix references to freed memory

mainline inclusion
from mainline-v6.10-rc6
commit 97ab304ecd95c0b1703ff8c8c3956dc6e2afe8e1
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGELE
CVE: CVE-2024-41069

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=97ab304ecd95c0b1703ff8c8c3956dc6e2afe8e1



--------------------------------

Most users after parsing a topology file, release memory used by it, so
having pointer references directly into topology file contents is wrong.
Use devm_kmemdup(), to allocate memory as needed.
