i3c: master: svc: report timeout waiting for STOP idle

svc_i3c_master_xfer() emits STOP or force-exit for the final transfer
and then waits for the controller state to become idle, but ignores
readl_poll_timeout(). The function can therefore return success while
the controller is still not idle.

Return the idle-wait error through the existing warning/FIFO cleanup
path so the caller observes the failed transfer without emitting a
second STOP after the final STOP or force-exit has already been sent.
