The 'ret' variable is used to store the integer return value of
ocfs2_get_clusters(), as shown by this warning from modern
compilers:

fs/ocfs2/aops.c: In function 'ocfs2_range_has_holes':
fs/ocfs2/aops.c:2437:11: error: comparison of constant '0' with boolean expression is always false [-Werror=bool-compare]

Fixes: mmotm ("ocfs2-fall-back-to-buffer-io-when-append-dio-is-disabled-with-file-hole-existing-fix")

I think this patch is not fit for mainline and will not be apply to mainline in the future.
Andrew can remove it from mm-tree.

Thanks,
Alex
