swap: cond_resched in swap_cgroup_prepare()
commit ef70762948dde012146926720b70e79736336764 upstream.
I saw need_resched() warnings when swapping on large swapfile (TBs)
because continuously allocating many pages in swap_cgroup_prepare() took
too long.
We already cond_resched when freeing page in swap_cgroup_swapoff(). Do
the same for the page allocation.
