Re: [PATCH for-4.15 1/5] tools/xenstored: Avoid unnecessary talloc_strdup() in do_control_lu()

At the moment, the return of talloc_strdup() is not checked. This means
we may dereference a NULL pointer if the allocation failed.

However, it is pointless to allocate the memory as send_reply() will
copy the data to a different buffer. So drop the use of talloc_strdup().

This bug was discovered and resolved using Coverity Static Analysis
