Log:
libnv: Don't lose big-endian flag when receiving a message.
A bug caused the "big endian" flag to be lost when receiving a message. As a
result, the bits are interpreted as little endian and an extremely large
allocation is attempted.
This change fixes ping(8)'s communication to casperd(8) on big-endian
architectures.
