Subject: [PATCH v1 2/2] i3c: master: svc: Recycle unused ibi slot

From: Stanley Chu <yschu@...oton.com>

In svc_i3c_master_handle_ibi(), an IBI slot is fetched from the pool
to store the IBI payload. However, when an error condition is encountered,
the function returns without recycling the IBI slot, resulting in an IBI
slot leak.
