[PATCH -next] reset: Remove unused variables

[Paul E. McKenney]

Neither reset_lookup_mutex nor reset_lookup_list are used anymore, which
results in build errors, so remove them.  It would be best if this were
to be folded into commit 205b261463ff ("reset: remove legacy reset lookup
code"), the better for bisection efforts.

Reproduce on armv8 with:

tools/testing/selftests/rcutorture/bin/torture.sh --duration 10 --do-none --do-rt

Fixes: 205b261463ff ("reset: remove legacy reset lookup code") # -next
