cpu/hotplug: Remove unused check_for_tasks() function

clang -Wunused-function found one remaining function that was
apparently meant to be removed in a recent code cleanup:

kernel/cpu.c:565:20: warning: unused function 'check_for_tasks' [-Wunused-function]

Sebastian explained: The function became unused unintentionally, but there
is already a failure check, when a task cannot be removed from the outgoing
cpu in the scheduler code, so bringing it back is not really giving any
extra value.

Fixes: 530e9b76ae8f ("cpu/hotplug: Remove obsolete cpu hotplug register/unregister functions")
