remoteproc: k3-dsp: Drop check performed in k3_dsp_rproc_{mbox_callback/kick}
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.
