Daniel Theophanes 44f9a3566c database/sql: fix deadlock test in prepare statement 
The issue go#46783 correctly diagnosed the context timeout
caused an intermittent failure when the context was canceled
prior to the BeginTx call. However due to the asynchronous nature
of canceling a Tx through a context on fast systems, the tx.Prepare
also succeeded. On slower systems or if a time.Sleep was inserted
between the BeginTx and Prepare, the Prepare would fail.

Resolve this by moving the context cancel after the Prepare.
This will still trigger the deadlock which I tested locally.
In addition, I interspersed multiple time.Sleep calls and the
test still functioned.

Fixes #46852
