ceph: add additional size check in ceph_setattr()
ceph_setattr() finally calls vfs function inode_newsize_ok()
to do offset validation and that is based on sb->s_maxbytes.
Because we set sb->s_maxbytes to MAX_LFS_FILESIZE to through
VFS check and do proper offset validation in cephfs level,
we need adding proper offset validation before calling
inode_newsize_ok().
