percpu: remove @may_alloc from pcpu_get_pages()
pcpu_get_pages() creates the temp pages array if not already allocated
and returns the pointer to it. As the function is called from both
[de]population paths and depopulation can only happen after at least
one successful population, the param doesn't make any difference - the
allocation will always happen on the population path anyway.
Remove @may_alloc from pcpu_get_pages(). Also, add an lockdep
assertion pcpu_alloc_mutex instead of vaguely stating that the
exclusion is the caller's responsibility.
