[svn-r8962] Purpose:

    Bug fix

Description:
    Allow I/O on extendible chunked datasets with (currently) zero-sized
dimensions to proceed harmlessly instead of dumping core on an assertion.

Solution:
    Removed assertion and added checks to avoid problem situation in H5TB_end

Platforms tested:
    FreeBSD 4.10 (sleipnir) w/ & w/o parallel
    Too minor to require h5committest
