ASoC: fsl_ssi: let check zero instead of check NO_IRQ
NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm, sh ...), and either may not be defined in some architectures which can enable SND_SOC_FSL_SSI (e.g. allmodconfig for arc). When irq_of_parse_and_map() fails, it will always return 0, so need check zero instead of NO_IRQ, or will cause compiling issue or run time bug in some architectures.
