LoongArch: Handle KCOV __init vs inline mismatches 



When the KCOV is enabled all functions get instrumented, unless
the __no_sanitize_coverage attribute is used. To prepare for
__no_sanitize_coverage being applied to __init functions, we have to
handle differences in how GCC's inline optimizations get resolved.
For LoongArch this exposed several places where __init annotations
were missing but ended up being "accidentally correct". So fix these
cases.
