btrfs: add support for inserting raid stripe extents
Add support for inserting stripe extents into the raid stripe tree on
completion of every write that needs an extra logical-to-physical
translation when using RAID.
Inserting the stripe extents happens after the data I/O has completed,
this is done to
a) support zone-append and
b) rule out the possibility of a RAID-write-hole.
