soc: qcom: ssr: Initialize the shutdown_ack completion variable properly 



The shutdown_ack completion varaible, used during a call to
sysmon_send_shutdown(), is not initialized correctly. Initialize
it first while a subsystem regsiters with the SSR framework, followed
by a reinitialization before every wait_for_completion(). This gives
the flexibility for any subsystem that registers with the SSR
framework to make a call to sysmon_send_shutdown.
