xfs: port the defer ops capture and continue to resource capture
When log recovery tries to recover a transaction that had log intent
items attached to it, it has to save certain parts of the transaction
state (reservation, dfops chain, inodes with no automatic unlock) so
that it can finish single-stepping the recovered transactions before
finishing the chains.
This is done with the xfs_defer_ops_capture and xfs_defer_ops_continue
functions. Right now they open-code this functionality, so let's port
this to the formalized resource capture structure that we introduced in
the previous patch. This enables us to hold up to two inodes and two
buffers during log recovery, the same way we do for regular runtime.
With this patch applied, we'll be ready to support atomic extent swap
which holds two inodes; and logged xattrs which holds one inode and one
xattr leaf buffer.
