net: netif_set_real_num_rx_queues may cap num_rx_queues at init time
Do not set num_rx_queues in netif_set_real_num_rx_queues() some
drivers will increase the real_num_rx_queues later due to a feature
changes or available interrupts increasing. By setting num_rx_queues
here this ends up creating a cap on the number of rx queues
available.
For example the ixgbe driver sets the max number of queues it intends
to use ever then sets the current number in use with the
netif_set_num_{rx|tx}_queues calls. With the current implementation
the number of rx queues gets limited so when a feature such as DCB
or FCoE is enabled the queues are no longer available.
kobjects will only be allocated for real_num_rx_queues so the waste
in memory is minimal.

cfg80211: fix BSS double-unlinking
When multiple interfaces are actively trying
to associate with the same BSS, they may both
find that the BSS isn't there and then try to
unlink it. This can cause errors since the
unlinking code can't currently deal with items
that have already been unlinked.
Normally this doesn't happen as most people
don't try to use multiple station interfaces
that associate at the same time too.
Fix this by using the list entry as a flag to
see if the item is still on a list.

Revert "iwlwifi: do not perferm force reset while doing scan"
This reverts commit
7acc7c683a747689aaaaad4fce1683fc3f85e552. It was
applied to avoid possible warning in ieee80211_restart_hw, however
reason of the warning were races in mac80211, currently hopefully fixed.
Not reseting device when performing scan is bad for two reasons.
When forcing reset from iwl_check_stuck_queue(), in case of fail,
reset will be repeated until scan finish. But since firmware is in bad
shape, scan only finish after scan_check work (about 7s). So we will
delay the reset, what is not good behaviour.
When forcing reset from iwl_recover_from_statistics(), we will not
repeat the reset, so we will not perform reset at all when needed.

When cfg80211 request the scan and mac80211 perform some management work,

caif: fix two caif_connect() bugs
caif_connect() might dereference a netdevice after dev_put() it.
It also doesnt check dev_get_by_index() return value and could
dereference a NULL pointer.
Fix it, using RCU to avoid taking a reference.
