This commit disables SMB2/3 lease support globally when multiprotocol SMB shares are enabled. This is because despite kernel_oplocks being a per-share parameter in libsmbconf, it is incompatible with SMB2/3 lease support and can lead to unexpected failures depending on the order in which the SMB client has negotiated its first SMB tree connect. Validation logic is simplified by making this share type mutually exclusive with AAPL extension support because timemachine -- the main driver for enabling this -- requires SMB2/3 lease support. (cherry picked from commit 0513234)
