xfs: fix memcpy fortify errors in RUI log format copying
Starting in 6.1, CONFIG_FORTIFY_SOURCE checks the length parameter of
memcpy. Since we're already fixing problems with BUI item copying, we
should fix it everything else.
Refactor the xfs_rui_copy_format function to handle the copying of the
head and the flex array members separately. While we're at it, fix a
minor validation deficiency in the recovery function.
