xfs: support non-power-of-two rtextsize with exchange-range

The VFS exchange-range alignment checks use (fast) bitmasks to perform
block alignment checks on the exchange parameters.  Unfortunately,
bitmasks require that the alignment size be a power of two.  This isn't
true for realtime devices, so we have to copy-pasta the VFS checks using
long division for this to work properly.
