mailbox: zynqmp-ipi: Remove dev.parent check in zynqmp_ipi_free_mboxes

Browse source

[ Upstream commit 019e3f4550 ]

The ipi_mbox->dev.parent check is unreliable proxy for registration
status as it fails to protect against probe failures that occur after
the parent is assigned but before device_register() completes.

device_is_registered() is the canonical and robust method to verify the
registration status.

Remove ipi_mbox->dev.parent check in zynqmp_ipi_free_mboxes().
