ocfs2: eliminate a misreported warning
The warning is invalid because the parameter chunksize passed from
ocfs2_info_freefrag_scan_chain-->ocfs2_info_update_ffg is guaranteed to
be positive. So __ilog2_u32 cannot return -1.
fs/ocfs2/ioctl.c: In function 'ocfs2_info_update_ffg':
fs/ocfs2/ioctl.c:411:17: warning: array subscript is below array bounds [-Warray-bounds]
hist->fc_chunks[index]++;
