Richard Yao 9e2be2dfbd Fix potential NULL pointer dereference regression 
945b407486 neglected to `NULL` check
`tx->tx_objset`, which is already done in the function. This upset
Coverity, which complained about a "dereference after null check".

Upon inspection, it was found that whenever `dmu_tx_create_dd()` is
called followed by `dmu_tx_assign()`, such as in
`dsl_sync_task_common()`, `tx->tx_objset` will be `NULL`.
