Fix MKLDNN BatchNorm with even number of channels (apache#19150)
77ccf78 
Even number of channels results in data reordering before batch
norm operation. Therefore, if BatchNorm data array is view of
another array and the data is stored in MKLDNN format, the data
needs to be converted to the default format.

Bug fixes are still ok until we finish the license issues.

Can someone confirm this fix has already been ported to the 1.x branch already before we merge this?
