Subject: [PATCH] farsync: remove redundant variable txq_length

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

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

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