This PR addresses the issue #8789
The original issue is disconnectPhysicalDiskByPath() implementation in FibreChannelAdaptor always returns true irrespective of the success of the operation. This was already fixed in the PR #8889 .
Ideally this method has to be called after choosing the right adapter based on the storage pool type of the volume path, but currently it is just called in a loop.

while trying to fix the case of running into the loop of all adapters by somehow passing the storage pool type to that caller cleanup() method but this is touching all over the code (which I fear it creates other regressions), instead I feel we can keep it the current way only since Fibrechannel adapter has already fixed.
In this PR I've added the java doc explaining the method and situation.
