ARM: 9207/1: amba: fix refcount underflow if amba_device_add() fails

"ARM: 9192/1: amba: fix memory leak in amba_device_try_add()" leads
to a refcount underflow if amba_device_add() fails, which called by
of_amba_device_create(), the of_amba_device_create() already exists
the error handling, so amba_put_device() only need to be added into
amba_deferred_retry().
