In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver
rtl8192ce are reported. One fix (commit a9b89e2) has already been applied,
and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.
Driver rtl8192de also has the same code structure - this one is fixed as well.

John,
This bug fix should be applied to 3.4. It has been in these drivers from
the beginning, and is not a regression.
