i3c: master: svc: Recycle unused IBI slot

[ Upstream commit 3448a934 ]

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.
