When 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". Fix these cases and force one function to be inline with __always_inline.
