diag: Fix race condition in diagchar driver

diag driver maintains socket logging process in global driver
structure which is manipulated in switch_logging and in close
file_operation.
There is a possibility of race while clearing the socket logging
process in close operation and sending signal in switch_logging
operation. Adding lock to serialize the two operations.

tty: n_smux: After receiving OPEN_ACK flush tx_queue

If a local SMUX client re-opens the channel and tries to send data before
receiving the OPEN_ACK, the transaction will get stuck because the
channel local state is not OPENED.

Add the channel to ready list if tx_queue is not empty after receiving
the OPEN_ACK.

cfg80211/nl80211: add API for MAC address ACLs

Add API to enable drivers to implement MAC address based
access control in AP/P2P GO mode. Capable drivers advertise
this capability by setting the maximum number of MAC
addresses in such a list in wiphy->max_acl_mac_addrs.

An initial ACL may be given to the NL80211_CMD_START_AP
command and/or changed later with NL80211_CMD_SET_MAC_ACL.

Black- and whitelists are supported, but not simultaneously.
