Michael Sproul 74eb267643 Remove double-locking deadlock from HTTP API (#4687) ...

## Issue Addressed

Fix a deadlock introduced in #4236 which was caught during the v4.4.0 release testing cycle (with thanks to @paulhauner and `gdb`).

## Proposed Changes

Avoid re-locking the fork choice read lock when querying a state by root in the HTTP API. This avoids a deadlock due to the lock already being held.

## Additional Info

The [RwLock docs](https://docs.rs/lock_api/latest/lock_api/struct.RwLock.html#method.read) explicitly advise against re-locking:

> Note that attempts to recursively acquire a read lock on a RwLock when the current thread already holds one may result in a deadlock.
