btrfs: extend btrfs_set_extent_delalloc and its friends to support in-band dedupe and subpage size patchset

Browse Source 
Extend btrfs_set_extent_delalloc() and extent_clear_unlock_delalloc()
parameters for both in-band dedupe and subpage sector size patchset.

This should reduce conflict of both patchset and the effort to rebase
them.
