ASoC: fsl_xcvr: free IRQ before canceling reset work
irq0_isr() schedules work_rst on a preamble error, and reset_rx_work()
touches regmap. remove() cancels that work while the IRQ is still
registered, so the handler can queue it again during teardown. The IRQ
is also requested before INIT_WORK() and spin_lock_init(). Probe
failure does not call remove(), so freeing the IRQ leaves queued work
running, and an earlier interrupt schedules uninitialized work.
Initialize the lock and devm_work_autocancel() before the IRQ. Failed
probe then frees the IRQ and cancels the work. Unbind frees the IRQ
before cancel_work_sync() and pm_runtime_disable().
Fixes: 1e5d0f106164 ("ASoC: fsl_xcvr: reset RX dpath after wrong preamble")
