remoteproc: Drop wait in __rproc_boot()
In the event that rproc_boot() is called before the firmware loaded
completion has been flagged it will wait with the mutex held,
obstructing the request_firmware_nowait() callback from completing the
wait.
As rproc_fw_config_virtio() has been reduced to only triggering
auto-boot there is no longer a reason for waiting in rproc_boot(), so
drop this.
