wlan: Stack Canary corruption

Stack canary gets override when longer length data variable is copied
to shorter length stack data variable. This leads to stack check fail
and finally kernel panic.
Stack canary protection is enabled with CC_STACKPROTECTOR_STRONG GCC
compilation flag. With regular protection option this issue will go
unnoticed.
