xfs: actually recover intended file sizes in xfs_xmi_item_recover_intent

Browse source

LOLLM points out that xfs_xmi_item_recover_intent doesn't actually
restore the isize1 and isize2 fields that were recovered from an
unfinished exchmaps log intent item.  Instead, xfs_exchmaps_init_intent
sets the wrong isize values from the recovered inodes, with the result
that the file sizes are not set correctly when item recovery finishes.
Fix this by restoring isize[12] from the log item.
