btrfs: defer I/O completion based on the btrfs_raid_bio
Instead of attaching an extra allocation an indirect call to each
low-level bio issued by the RAID code, add a work_struct to struct
btrfs_raid_bio and only defer the per-rbio completion action. The
per-bio action for all the I/Os are trivial and can be safely done
from interrupt context.
As a nice side effect this also allows sharing the boilerplate code
for the per-bio completions
