netif_carrier was only supposed to be used in client mode, but this was
indeed broken at least with some firmware versions. I think I tested
this with some firmware version when the change was added to CVS and it
seemed to be working in Master mode.. Anyway, I was able to reproduce
the problem case easily with the current firmware release and the devel
snapshot of the driver.

I committed couple of changes to disable netif_carrier_off() calls in
non-client modes. In addition, SIOCSIWMODE handler is now calling
netif_carrier_on() when moving to non-client mode.

I have not tested all combinations yet and would appreciate it if you
could test the current development snapshot and report whether it works
in your setup. I did not yet merge the changes to stable branch, but I
will do this before 0.2.5 release if these seem to fix the problem.
