Make QDir::mkpath() return true when given an existing drive name

Browse Source 
Commit ed48391c592e8ba68c723e3017ac384f0c7a7c23 removed the check for
ERROR_ACCESS_DENIED reported by the Windows CreateDirectory(...)
function in case an existing windows drive name was passed as argument.
This restores the behavior of the function which broke after 5.15.

Pick-to: 6.2
Fixes: QTBUG-85997
