An async shutdown during init is confusing when a simple boolean return value can be used for a synchronous shutdown.

This also changes the error message on stderr from:

Error: A fatal internal error occurred, see debug.log for details
Error: A fatal internal error occurred, see debug.log for details

To:

Error: basic block filter index best block of the index goes beyond pruned data. Please disable the index or reindex (which will download the whole blockchain again)

Code review ACK—however this introduces two warnings here locally:

…/bitcoin/src/test/coinstatsindex_tests.cpp:35:5: warning: ignoring return value of function declared with 'nodiscard' attribute [-Wunused-result]

Check return value of name-hash index start.

Check the return value when starting the name-hash index, and properly
handle a failure.  This is an addition to the upstream changes from
bitcoin/bitcoin#21796 for Namecoin.
