[PATCH]remove dead code in bcm43xx_sysfs.c (wireless-2.6)

[Larry Finger <Larry.Finger@lwfinger.net>]

John,

Please queue this patch to remove dead code from bcm43xx-softmac in wireless-2.6. It was submitted
by Darren Jenkins based on a Coverity code checker report. I had to revise the patch for the 2.6.18 
locking model, and have tested it.

Thanks,

Larry
