Merge bitcoin/bitcoin#22895: consensus: don't call GetBlockPos in ReadBlockFromDisk without cs_main lock
350e034e64d175f3db4c85ddca42e76e279912f6 consensus: don't call GetBlockPos in ReadBlockFromDisk without lock (Jon Atack)
Pull request description:
Commit ccd8ef65 "Reduce cs_main lock in ReadBlockFromDisk, only read GetBlockPos under the lock" in #11281 moved the cs_main lock from caller to `ReadBlockFromDisk()` for calling `CBlockIndex::GetBlockPos()`, but the second invocation doesn't have the lock, and IIUC there is no guarantee the compiler can know if state has changed.
Use the `blockPos` local variable instead, rename it to `block_pos`, and make it const.
