[PATCH] softmac: remove netif_tx_disable when scanning

In the scan section of ieee80211softmac, network transmits are disabled.
When SoftMAC re-enables transmits, it may override the wishes of a driver
that may have very good reasons for disabling transmits. At least one failure
in bcm43xx can be traced to this problem. In addition, several unexplained
problems may arise from the unexpected enabling of transmits.
