soc: qcom: glink_ssr: Set NULL after free
In function close_ch_worker variable ss_info->cb_data is not set to NULL after free, this results in crash due to use after free in notify_for_subsystem function. This variable is set to NULL to avoid any crash due to use after free. CRs-Fixed: 2000384 Change-Id: Ia0c7b52e4c8f5d0215fd0ebfbca5e823530f205c Signed-off-by: Dhoat Harpal <hdhoat@codeaurora.org>
