Quorum queues: fix error logging during node drain

[majialoong]

Proposed Changes

This PR fixes two error log calls in rabbit_quorum_queue that used a ~tp format placeholder but did not provide any formatting arguments.

Types of Changes

• Bug fix (non-breaking change)

Checklist

Further Comments

This is a small, localized fix: keep the existing log message, only add the missing argument lists ([RaLeader] / [RaNode]) to match the ~tp placeholder.

@majialoong thanks. Do I understand it correctly that a CLA signing request yesterday was from you?

FTR, this issue comes from commit e408c9e and does not apply beyond v4.2.x because, well, that commit was introduced in the 4.2.0 cycle.
