Subject: [PATCH] thunderbolt: Fix memory leak if ida_simple_get() fails in enumerate_services()
Git-commit: a663e0df4a374b8537562a44d1cecafb472cd65b
Patch-mainline: v5.10-rc4
References: git-fixes

The svc->key field is not released as it should be if ida_simple_get()
fails so fix that.

Fixes: 9aabb68568b4 ("thunderbolt: Fix to check return value of ida_simple_get")
