nfsd: fix double fget() bug in __write_ports_addfd()
The bug here is that you cannot rely on getting the same socket
from multiple calls to fget() because userspace can influence
that. This is a kind of double fetch bug.
The fix is to delete the svc_alien_sock() function and instead do
the checking inside the svc_addsock() function.
Fixes: 3064639423c4 ("nfsd: check passed socket's net matches NFSd superblock's one")
