drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit()
commit 3a47f4b439beb98e955d501c609dfd12b7836d61 upstream.
The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32
values that come from the user via the submit_lookup_cmds() function.
This addition could lead to an integer wrapping bug so use size_add()
to prevent that.
