percpu: free percpu allocation info for uniprocessor system

commit 3189eddbcafcc4d827f7f19facbeddec4424eba8 upstream.

Currently, only SMP system free the percpu allocation info.
Uniprocessor system should free it too. For example, one x86 UML
virtual machine with 256MB memory, UML kernel wastes one page memory.
