Eric Blake 73e064ccf0 nbd: Fix regression with multiple meta contexts ... Detected by a hang in the libnbd testsuite. If a client requests multiple meta contexts (both base:allocation and qemu:dirty-bitmap:x) at the same time, our attempt to silence a false-positive warning about a potential uninitialized variable introduced botched logic: we were short-circuiting the second context, and never sending the NBD_REPLY_FLAG_DONE. Combining two 'if' into one 'if/else' in bdf200a55 was wrong (I'm a bit embarrassed that such a change was my initial suggestion after the v1 patch, then I did not review the v2 patch that actually got committed). Revert that, and instead silence the false positive warning by replacing 'return ret' with 'return 0' (the value it always has at that point in the code, even though it eluded the deduction abilities of the robot that reported the false positive).
