[PATCH 4/5] ASoC: fsl_asrc: Request the IRQ after the device is initialized

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

Request the IRQ after fsl_asrc_init(), while the device is still
runtime active, so that the interrupt handler cannot run before
the device is initialized.

If requesting the IRQ fails, balance the runtime PM usage count
before proceeding with cleanup.
