nvmet: fix discover log page when offsets are used

2019-04-11T15:28:30Z

The nvme target hadn't been taking the Get Log Page offset parameter into consideration, and so has been returning corrupted log pages when offsets are used. Since many tools, including nvme-cli, split the log request to 4k, we've been breaking discovery log responses when more than 3 subsystems exist. Fix the returned data by internally generating the entire discovery log page and copying only the requested bytes into the user buffer. The command log page offset type has been modified to a native __le64 to make it easier to extract the value from a command.
