ksmbd: send proper error response in smb2_tree_connect()
Currently, smb2_tree_connect doesn't send an error response packet on
error.
This causes libsmb2 to skip the specific error code and fail with the
following:
smb2_service failed with : Failed to parse fixed part of command
payload. Unexpected size of Error reply. Expected 9, got 8
