i2c: core: fix lockdep warning for sparsely nested adapter chain
When adapters are chained in a sparse manner (with intermediate MFD devices,
for instance) the code currently fails to use the correct subclass for
the adapter's bus_lock which leads to false-positive lockdep warnings.
Fix this by walking the entire pedigree of the device and count all
adapters along the way instead of just checking the immediate parent.
