sock_diag: remove sock_diag_mutex
sock_diag_rcv() is still serializing its operations using
a mutex, for no good reason.
This came with commit 0a9c73014415 ("[INET_DIAG]: Fix oops
in netlink_rcv_skb"), but the root cause has been fixed
with commit cd40b7d3983c ("[NET]: make netlink user -> kernel
interface synchronious")
Remove this mutex to let multiple threads run concurrently.
