Avi Kivity 67c4d980dd Revert "Merge 'auth: move passwords::check call to alien thread' from Andrzej Jackowski"
This reverts commit 1fd82d32e0. It causes
connection storms to snowball into a node crash via this mechanism:

1. large node suffers mild connection storm
2. password hash requests queue up on alien hash thread
3. incoming hash requests queue faster than the alien thread can retire them.
4. auth latency grows without bounds
5. this encourages the clients to create new connections
6. problem grows

Reverting the patch restores the hash stall, but at least prevents node
crashes.

Fixes #26461 (2025.1)

Closes scylladb/scylladb#26462
