msm: kgsl: Check user generated timestamp before queuing drawobjs

In ioctls like kgsl_ioctl_submit_commands(), if both syncobj
type and cmd/marker/sparseobj type are submitted, the syncobj
is queued first followed by the other obj type. After syncobj
is successfully queued, in case of failure in get_timestamp
while queuing the other obj, both the command objs are
destroyed. As sync obj is already queued, accessing this
later would cause a crash.

Compare the user generated timestamp with the drawctxt
timestamp and return early in case of error. This avoids
unnecessary queuing of drawobjs.
