[PATCH][SMB3] workaround negprot bug in some Samba servers by changing order of negcontexts sent by Linux kernel client

Starting with 5.18.8 (and 5.19-rc4) mount can now fail to older Samba
servers due to a server bug handling padding at the end of the last
negotiate context (negotiate contexts typically round up to 8 byte
lengths by adding padding if needed). This server bug can be avoided
by switching the order of negotiate contexts, placing a negotiate
context at the end that does not require padding (prior to the recent
netname context fix this was the case on the client).

Fixes: 73130a7b1ac9 ("smb3: fix empty netname context on secondary channels")

See attached fix to cifs.ko
