staging/lustre/llite: Fix integer overflow in ll_fid2path
Reported by Dan Carpenter <dan.carpenter@oracle.com>
outsize = sizeof(*gfout) + gfin->gf_pathlen;
Where outsize is int and gf_pathlen is u32 from userspace
can lead to integer overflowwhere outsize is some small number
less than sizeof(*gfout)
Add a check for pathlen to be of sensical size.
