video: tegra: nvmap: Disable read/write APIs for prod_nsr

Browse Source 
NvRmMemRead/NvRmMemWrite APIs don't have corresponding requirements in
DriveOS 7.0 Linux NSR. We have taken sign-off from the stakeholders to
confirm that they are not using these APIs in T264 Linux Prod NSR
variant. But some of them are using these APIs in dev_nsr and did not
agree to remove it from dev-nsr, L4T, HOS etc. Hence we need to
make sure that they do not accidentally start using these APIs. Add
bug_on when the corresponding ioctl is called in prod_nsr.
