Andrew Clayton 30b410e490 Avoid a segfault in nxt_conn_io_sendbuf() ...

This is a simple temporary fix (doesn't address the underlying problem)
for an issue reported by a user on GitHub whereby downloading of files
from a PHP application would cause the router process to crash.

This is actually a generic problem that will affect anything sending
data via nxt_unit_response_write().

This is just a simple fix for the 1.32 release, after which the full
correct fix will be worked out.
