qcacld-3.0: Save and restore SAR config post SSR

After SSR, SAR configuration is lost.
Since, SSR is hidden from userland, VENDOR_SUBCMD_SET_SAR_LIMITS
to configure SAR shall not come again from userspace after SSR.

To restore SAR configuration, save this in hdd context when the vendor
command comes and restore after re-init.
