dsp: lsm: Initialize lock and condition before apr_register

While allocating lsm client, lock and conditions are initialized
after registering session with APR. There is a possibility of
accessing uninitialized condition from q6lsm_callback when SSR
is triggerred after the port specific apr is registered.

Initialized lock, condition and state before registering session
with APR to avoid invalid access.
