ufs: fix logics in "ufs: make fsck -f happy"
Storing stats _only_ at new locations is wrong for UFS1; old locations should always be kept updated. The check for "has been converted to use of new locations" is also wrong - it should be "->fs_maxbsize is equal to ->fs_bsize". Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
