[PATCH] net/hamradio/6pack: remove redundant variable channel

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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

Cleans up two clang warnings:
warning: variable 'channel' set but not used [-Wunused-but-set-variable]
