target: Don't call TFO->write_pending if data_length == 0
commit 885e7b0e181c14e4d0ddd26c688bad2b84c1ada9 upstream.
If an initiator sends a zero-length command (e.g. TEST UNIT READY) but
sets the transfer direction in the transport layer to indicate a
data-out phase, we still shouldn't try to transfer data. At best it's
a NOP, and depending on the transport, we might crash on an
uninitialized sg list.
