[PATCH] drivers: net: lmc: remove redundant variable next_rx

[PATCH] drivers: net: lmc: remove redundant variable next_rx

[Colin King]

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

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

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