[svn-r4494] Purpose:
    Bug fix.

Problem:
    When an entire dataset was selected (through whatever means, H5S_ALL, making
    an explicit "all" selection, etc.), the code was not allowing the optimized
    routine to read the entire dataset in at once when the current dimensions
    did not match the maximum dimensions and instead was defaulting to a [much]
    slower method to read in the dataset.

Solution:
    Took out check which was requiring current dimensions to be equal to the
    maximum dimensions.

Platforms tested:
    FreeBSD 4.4 (hawkwind)
