Larry Finger 7dcdd073bf rtl8187: Fix lockups due to concurrent access to config routine 
Some users of the RTL8187B have experienced difficulties since commit
49292d5635 that introduced the power
management wext hooks. This difficulty has not made much sense until
it was realized that it was possible for mac80211 to make a call to the
config routine while that routine was already being executed. On this
device, it is necessary to loopback the TX when changing channels. Unless
this is properly restored, the device will lockup. A mutex now protects
the device state, and the private data in several places.

The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>,
who also suggested this type of fix.
