Richard Yao 8532da5e20 Cleanup: Delete dead code from send_merge_thread()
range is always deferenced before it reaches this check, such that the
kmem_zalloc() call is never executed.

A previously version of this had erronously also pruned the
`range->eos_marker = B_TRUE` line, but it must be set whenever we
encounter an error or are cancelled early.

Coverity incorrectly complained about a potential NULL pointer
dereference because of this.
