Add missing cs_main lock to ::GETBLOCKTXN processing

Note that this is not a major issue as, in order for the missing lock to cause issues, you have to receive a GETBLOCKTXN message while reindexing, adding a block header via RPC, etc, which results in either a table rehash or an insert into the bucket which you are currently looking at.
