XL: return false only if given prefix doesn't exist in all disks (#1877) 

Previously xl.isObject() returns false if one of the disk doesn't have
the object.  Its possible that object may be present in another disk.

This patch fixes the issue by returning false only if given prefix
doesn't exist in all disks.

Fixes #1855
