Amir Goldstein 7bcd74b98d ovl: check if all layers are on the same fs ...

Some features can only work when all layers are on the same fs.  Test this
condition during mount time, so features can check them later.

Add helper ovl_same_sb() to return the common super block in case all
layers are on the same fs.
