ASoC: sti: initialize IRQ lock before requesting IRQ

Browse source

uni_reader_init() registers the shared IRQ before initializing
reader->irq_lock. A pending interrupt can invoke the handler while the
lock is still uninitialized.

Initialize the lock before registering the IRQ so the interrupt path
always sees valid lock state.
