Fix unused variable warning in if_alc.c
With clang 15, the following -Werror warning is produced:
sys/dev/alc/if_alc.c:3441:6: error: variable 'prog' set but not used
[-Werror,-Wunused-but-set-variable]
int prog;
^
The 'prog' variable seems to be a left-over from some debugging code
that no longer exists, and can be removed without any functional change.
