Al noted in [1] that fd_install can't be undone, so it must come last in the fd translation sequence, only after we've successfully reserved all descriptors and copied them into the transaction buffer. This patch takes Al's proposed fix in [2] and makes a few tweaks to fold the traversal of t->fd_fixups during release.
