afs: Fix potential null pointer dereference in afs_put_server 
afs_put_server() accessed server->debug_id before the NULL check, which
could lead to a null pointer dereference. Move the debug_id assignment,
ensuring we never dereference a NULL server pointer.

Fixes: 2757a4dc18 ("afs: Fix access after dec in put functions")
