[ Upstream commit e0c49bd2b4d3cd1751491eb2d940bce968ac65e9 ]
sysv_nblocks() returns 'blocks' rather than 'res', which only counting the number of triple-indirect blocks and causing sysv_getattr() gets a wrong result.
[AV: this is actually a sysv counterpart of minixfs fix - 0fcd426de9d0 "[PATCH] minix block usage counting fix" in historical tree; mea culpa, should've thought to check fs/sysv back then...]
