Subject: [PATCH] net: bgmac: remove redundant variable 'freed'

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

Variable 'freed' is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'freed' set but not used [-Wunused-but-set-variable]
