different channel from the destination AP. Fix this by passing the
current wdev to rdev_fixed_channel() in the same way that was already
done for join-IBSS and connect commands. This allows the fixedchan
check to skipped for the current wdev and allows the reassociation to
proceed.

I'm not sure when exactly this issue showed up (i.e., whether this
reassociation case used to work or whether we managed to break it at
some point), but the EBUSY is certainly showing up very frequently
with the current wireless-testing.git snapshot in an environment with
large number of APs in the ESS and frequent roaming between them.
