ASoC: qcom: q6apm: clear g_apm on driver removal
The global g_apm pointer is set during apm_probe() but never cleared
in apm_remove(). After the driver is removed the devm-managed struct
q6apm is freed, leaving g_apm dangling. A subsequent call to
q6apm_is_adsp_ready() dereferences the freed pointer.
Clear g_apm in apm_remove() before the component is unregistered so
that q6apm_is_adsp_ready() returns false instead of triggering a
use-after-free.
