[PATCH] ALSA: ali5451: remove redundant pointer 'codec'

[Colin King]

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

Pointer 'codec' is being assigned but is never used hence it is
redundant and can be removed.

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