Prakash Surya ab11916583 OpenZFS 9456 - ztest failure in zil_commit_waiter_timeout 
Problem
=======

Illumos bug 8373 was integrated, which now presents a code path where
"dmu_tx_assign" can fail.  When "dmu_tx_assign" fails, it will not issue
the lwb that was passed in to "zil_lwb_write_issue".  As a result, when
"zil_lwb_write_issue" returns, the lwb will still be in the "opened"
state, just as it was when "zil_lwb_write_issue" was originally called.

Solution
========

As a result of this new call path, the failed assertion needs to be
modified to be aware of this new possibility. Thus, we can only assert
that the lwb is no longer in the "opened" state if the returned lwb is
non-null, since we cannot differentiate between the case of
"dmu_tx_assign" failing or "zio_alloc_zil" failing within the call to
"zil_lwb_write_issue".
