Eric Blake 76df2b8d69 nbd/server: Silence clang sanitizer warning
clang's sanitizer is picky: memset(NULL, x, 0) is technically
undefined behavior, even though no sane implementation of memset()
deferences the NULL.  Caught by the nbd-qemu-allocation iotest.

The alternative to checking before each memset is to instead force an
allocation of 1 element instead of g_new0(type, 0)'s behavior of
returning NULL for a 0-length array.
