This fixes a slab corruption issue in the ipw2200 driver: it essentially
multiplied the error log number _twice_ by the size of the error element
entry (once explicitly in the code, and once implicitly as part of the
regular pointer arithmetic).

The function ipw_request_direct_scan() should bail out when the device
is down. This fixes a lockup caused by wpa_supplicant triggering
ipw_request_direct_scan() while the driver was in a middle of a reset
due to firmware errors.
Thanks to Zilvinas Valinskas for reporting the bug and helping me
debug it.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

The problem is caused by the patch in bug455 -- Channel change flood
generates fatal error.
The patch set the DISASSOCIATING status bit after sending the command.
The process was scheduled out when waiting for the command to be sent to
the card. The disassociated notification clears the DISASSOCIATING bit
in the tasklet before the process set the bit.
Move the bit setting code before sending the command now.

Because of the frequent channel change, it is possible that when we are
try to associate with channel 1 (authenticated but not associated).
Another channel change comes at this time, then the driver will issue
disassociate command to the firmware which will cause the fatal error.
It seems that the association/disassociation procedure should not be
interrupted.
The patch attached adds test on STATUS_ASSOCIATING | STATUS_DISASSOCIATING
in ipw_send_cmd(), when ensures that commands will not be sent to firmware
when we are in these two status.
