sched: Remove never used code in mm_cid_get()

Browse Source 
[ Upstream commit 53abe3e1c1 ]

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 used along with the assignment
that does not have side effects as far as I can see.  Remove those
altogether.
