xfs: disable sparse inode chunk alignment check when there is no alignment

Browse Source 
While testing a 64k-blocksize filesystem, I noticed that xfs/709 fails
to rebuild the inode btree with a bunch of "Corruption remains"
messages.  It turns out that when the inode chunk size is smaller than a
single filesystem block, no block alignments constraints are necessary
for inode chunk allocations, and sb_spino_align is zero.  Hence we can
skip the check.
