compiler.h, kasan: Avoid duplicating __read_once_size_nocheck()
commit bdb5ac801af3d81d36732c2f640d6a1d3df83826 upstream.
Instead of having two identical __read_once_size_nocheck() functions
with different attributes, consolidate all the difference in new macro
__no_kasan_or_inline and use it. No functional changes.
