fsverity: fix build error by adding fsverity_readahead() stub
hppa-linux-gcc 9.5.0 generates a call to fsverity_readahead() in
f2fs_readahead() when CONFIG_FS_VERITY=n, because it fails to do the
expected dead code elimination based on vi always being NULL. Fix the
build error by adding an inline stub for fsverity_readahead(). Since
it's just for opportunistic readahead, just make it a no-op.
