Revert "Update downlink MCS table" block of code to function nr_set_pdsch_semi_static to get downlink working again in NSA

Merge remote-tracking branch 'origin/ubuntu_18_rt_add_san_incompatibility' into integration_2022_wk24

When we run with the RT scheduler and the address sanitizer in Ubuntu
18.04, pthread_create will hang and never create threads.  This adds
some explanatory text in CMakeLists.txt to explain about this issue.

Reset ul_failure flag only after sending Msg4 otherwise gNB starts scheduling too early
