[PATCH] iwlwifi: remove redundant assignment to variable bufsz

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

The variable bufsz is being initialized with a value that is never
read and it is being updated later with a new value. The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")

Thanks! I applied this to our internal tree and it will reach the
mainline following our usual upstreaming process.
