LOG: [compiler-rt][nsan] Remove unused checkValueConsistency template (NFC) (#207441)

checkValueConsistency is a static function template in nsan.cpp with no
callers, so it trips -Wunused-template. Remove the dead code.

Part of #202945

Added: 
    

Modified: 
    compiler-rt/lib/nsan/nsan.cpp

Removed:
