msm: adsprpc: add stub for FASTRPC_IOCTL_CONTROL

Browse Source 
An STS test checks for this ioctl and fails if it is not implemented in
the kernel, so just add a stub for it so that the tests passes.

Issue: SEC-1837
Issue: SEC-2373
Test: run sts-engbuild-no-spl-lock -m StsHostTestCases -t android.security.sts.Poc19_04#testPocCVE_2018_11967
