[PATCH] ASoC: fsl_asrc_m2m: fix pm_runtime usage counter leak on error

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

pm_runtime_get_sync() leaves the runtime PM usage counter incremented even
when it fails, but the error path in fsl_asrc_m2m_comp_open() does not
call pm_runtime_put_noidle() to balance it, leaking a reference each
time resume fails.

Use pm_runtime_resume_and_get() instead, which automatically drops the
usage counter on failure, fixing the leak.

Fixes: 24a01710f627 ("ASoC: fsl_asrc_m2m: Add memory to memory function")
