video: tegra: nvmap: Cleanup NVMAP_IOC_SET_TAG_LABEL ioctl

Browse Source 
NvRmMemSetAllocationTagLabel is not being used by any of clients. Also,
this API does not have any SHR or JAMA requirement. Hence we are
removing support for this API on linux to have a cleaner and uniform
ICD. Remove the corresponding ioctl code from nvmap.
