ASoC: cs35l41: Verify PM runtime resume errors in IRQ handler
The interrupt handler invokes pm_runtime_get_sync() without checking the
returned error code.
Add a proper verification and switch to pm_runtime_resume_and_get(), to
avoid the need to call pm_runtime_put_noidle() for decrementing the PM
usage counter before returning from the error condition.
Fixes: f517ba4924ad ("ASoC: cs35l41: Add support for hibernate memory retention mode")
