[svn-r7175] Purpose:

    Bug fix

Description:
    Boot block checksum was being used instead of file driver info checksum
    in one calculation.

    Also, the offset of the file driver info was hard-coded to the end of the
    superblock, instead of using the file driver offset variable.

Solution:
    Changed to use file driver checksum and file driver offset variable.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
    too small for h5committest
