[svn-r7234] Purpose:

    Bug fix

Description:
    When a non-default indexed storage B-tree internal 'K' value is set by the
user, the chunked datasets created in that file (until it is closed) use the
user's 'K' value and the data can be accessed correctly, but the 'K' value is
not stored in the file.
    However, once the file is closed and re-opened, the non-default 'K' value
is lost and the data in the chunked datasets will not be able to be accessed
correctly.

Solution:
    Store the indexed storage B-tree internal 'K' value in the superblock.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
