LU-17599 ldiskfs: restore ldiskfs patch attribution

Over time various ports of ldiskfs patches to newer kernel
releases and distribution kernels have lost or confused the
original history and author of many patches.  It is also
helpful to have a summary for the reason behind each patch.

Thanks-to: Andreas Dilger <adilger@whamcloud.com>
for digging through the history of these patches.
