NFSv4/pnfs: Support a list of commit arrays in struct pnfs_ds_commit_info

Browse Source 
When we have multiple layout segments with different lists of mirrored
data, we need to track the commits on a per layout segment basis.
This patch adds a list to support this tracking in struct
pnfs_ds_commit_info.
