perf: Fix unclone_ctx() vs. locking
The idiot who did 4a1c0f262f88 ("perf: Fix lockdep warning on process exit")
forgot to pay attention and fix all similar cases. Do so now.
In particular, unclone_ctx() must be called while holding ctx->lock,
therefore all such sites are broken for the same reason. Pull the
put_ctx() call out from under ctx->lock.
