SMB encryption does not work with macOS 11.4
Mac OS 11.4 introduced support for SMB 3.11 on the client side and with this SMB encryption is now broken again. The problem arises from our implementation forcing GCM when SMB 3.11 is in use, but Mac OS only supports CCM.

I have a fix our for review here: https://code.illumos.org/c/illumos-gate/+/1590
Testing: I ran a build of illumos with this fix applied in VMware Fusion and was able to connect to it from the host, which is a Mac Pro running macOS Big Sur 11.4. I copied some files to a share and used Wireshark to confirm that the traffic was encrypted. Before the connection dialog would just hang and rebooting the illumos VM or rebooting the host was the only way to unblock it.
