Merge bitcoin/bitcoin#22868: wallet: Call load handlers without cs_wallet locked
f13a22a631efe01e1fbae4ae78a4901d14ebda3c wallet: Call load handlers without cs_wallet locked (João Barbosa)
Pull request description:
Don't have `cs_wallet` locked while calling each `context.wallet_load_fns`. A load handler can always lock `cs_wallet` if needed.
The lock was added in 1c7e25db0c to satisfy TSAN. With 44c430ffac most of the code requiring the lock is in `CWallet::AttachChain`. A comment is added to warn about wallets_mutex and cs_wallet lock ordering.
