msm: ipa: rmnet: Update wan IOCTL function in SSR scenario



During SSR scenario in IP-PASS through config,
IPA driver miss to update lan client info.

Which is breaking IPACM functionality,
leads to data stall in lan stats enabled
with IP-PASS through.

Allow wan IOCTL function only for setting and
clearing the lan client info during SSR.
