hal: deadlock with pause and SSR for compressed offload

For compress offload playback, during SSR offline
callback will hold out and latch lock and set
offload state to idle and wait on compress
offload thread state to be marked as unblocked.

In the mean time pause is triggered and it acquires
out lock and waits for out_latch lock.

And in another thread compress_wait completes and
wait for out lock causing dead lock.

Fix this by moving latch lock to protect only
offload_state, so that latch lock can be released.
