[PATCH v1 1/1] sched: Remove never used code in mm_cid_get()

[Andy Shevchenko]

Clang is not happy with set but unused variable (this is visible
with `make W=1` build:

kernel/sched/sched.h:3744:18: error: variable 'cpumask' set but not used [-Werror,-Wunused-but-set-variable]

It seems like the variable was never be used along with the assignment that
does not have side effects as far as I can see. Remove those altogether.

Fixes: 223baf9d17f2 ("sched: Fix performance regression introduced by mm_cid")
