remoteproc: k3-dsp: Drop check performed in k3_dsp_rproc_{mbox_callback/kick}
[ Upstream commit 349d62ab207f55f039c3ddb40b36e95c2f0b3ed0 ] Commit ea1d6fb5b571 ("remoteproc: k3-dsp: Acquire mailbox handle during probe routine") introduced a check in the "k3_dsp_rproc_mbox_callback()" and "k3_dsp_rproc_kick()" callbacks, causing them to exit if the remote core's state is "RPROC_DETACHED". However, the "__rproc_attach()" function that is responsible for attaching to a remote core, updates the state of the remote core to "RPROC_ATTACHED" only after invoking "rproc_start_subdevices()". The "rproc_start_subdevices()" function triggers the probe of the Virtio RPMsg devices associated with the remote core, which require that the "k3_dsp_rproc_kick()" and "k3_dsp_rproc_mbox_callback()" callbacks are functional. Hence, drop the check in the callbacks.
