HealBucket was double counting endpoints (#6707)

Endpoint comparisons blindly without looking
if its local is wrong because the actual drive
for a local disk is always going to provide just
the path without the HTTP endpoint.

Add code such that this is taken care properly in
all situations. Without this PR HealBucket() would
wrongly conclude that the healing doesn't have quorum
when there are larger number of local disks involved.

Fixes #6703
