Verify that alternate superblocks have a correct magic number before
trying to use them. Set a minimum value for numdirs when using an
alternate superblock to avoid spurious numdirs == 0 error. Calculate
new fields when using an alternate superblock from a UFS1 filesystem
to avoid segment faulting.
