Merge bitcoin/bitcoin#22609: [GetTransaction] remove unneeded cs_main lock acquire
4a1b2a7ba7f804e656a8cd29d5aa80fcbd40904f [GetTransaction] remove unneeded `cs_main` lock acquire (Sebastian Falbesoner)
Pull request description:
This PR is a follow-up to #22383. For reading from the mempool, only `mempool.cs` needs to be locked (see [suggestion by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/22383#discussion_r675069128)):
https://github.com/bitcoin/bitcoin/blob/b620b2d58a55a88ad21da70cb2000863ef17b651/src/txmempool.h#L554-L558
`CTxMemPool::get()` acquires this lock:
https://github.com/bitcoin/bitcoin/blob/b620b2d58a55a88ad21da70cb2000863ef17b651/src/txmempool.cpp#L822-L829
so we don't need to acquire any lock ourselves in `GetTransaction()`, as the other functions called in the remaining parts also don't need to have `cs_main` locked.
