[PATCH] fsi: aspeed: release the master device node with the device

[Yige Jiang <yigejiang86@gmail.com>]

fsi_master_aspeed_probe() takes a node reference for master.dev.
The posted error-path fix releases it before directly freeing the
allocation, but the successful registration path still retains it
when the master device is finally released.

Put the node in aspeed_master_release() before freeing the containing
object. With the posted remove-path device put, this keeps the node
valid until the last master-device user is gone and balances the
successful path without repeating the error-path put.
