If cfg80211 requests to connect when we have already had an active
profile, invalidate the current profile first before sending a new
profile to UMAC.

When connect is called with the LEGACY_PSK authentication type set, and a
proper sme->key, we need to set the WEP key straight after setting the
profile otherwise the authentication will never start.

The device sends connection terminated and [re]association success
(or failure) events when roaming occours. The patch uses
cfg80211_roamed instead of cfg80211_connect_result to notify SME
for roaming.

When the driver receives "connection terminated" event from device,
it could be caused by 2 reasons: the firmware is roaming or the
connection is lost (AP disappears). For the former, an association
complete event is supposed to come within 3 seconds. For the latter,
the driver won't receive any event except the connection terminated.
So we kick a delayed work (5*HZ) when we receive the connection
terminated event. It will be canceled if it turns out to be a roaming
event later. Otherwise we notify SME and userspace the disconnection.

The LMAC calibration API got broken mostly by having a configuration bitmap
being different than the result one.
This patch tries to address that issue by correctly running calibrations with
the newest firmwares, and keeping a backward compatibility fallback path for
older firmwares, where the configuration and result bitmaps were identical.

When UMAC stalls or asserts, we want to reset the device. But when we're
associated, the current reset worker will end up calling
cfg80211_connect_result() with the cfg80211 sme layer knowing that we're
reassociating. That ends up with some ugly warnings.
With this patch we're telling the upper layer that we've roamed if
reassociation succeeds, and that we're disconnected if it fails.
