LOG: hwasan: fix buildbot breakage (unused functions)

This addresses another buildbot breakage:
https://lab.llvm.org/buildbot/#/builders/37/builds/22166

My patch, https://reviews.llvm.org/D150708 introduced
stubs for common interceptor macros; these had unused
variables and functions. An earlier patch fixed the
unused variables; this patch suppresses unused-functions
warnings.

Added: 
    

Modified: 
    compiler-rt/lib/hwasan/hwasan_interceptors.cpp

Removed:
