Add HCI_CONN_LE_SMP_PEND flag to indicate that SMP is pending
for that connection. This allows to have information that an SMP
procedure is going on for that connection.
We use the HCI_CONN_ENCRYPT_PEND to indicate that encryption
(HCI_LE_Start_Encryption) is pending for that connection.
While a SMP procedure is going on we hold an reference to the

The commit "mac80211: stop tx before doing hw config and
rate update" stops the tx queue and call drv_flush so frequently
whenever a beacon got received with 11n htcap. This leads to
massive "Failed to stop TX DMA" logspam on embedded hw. So the
queue stop and flush should be called if and only if there is a
change in the channel type.

Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.
This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.
Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.
This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD'
I have seen in P2P testing, but it is likely
that there are other errors caused by this.
