Vasily Averin 113737cc31 mm/swapfile.c: use kvzalloc for swap_info_struct allocation ...

commit 873d7bcfd066663e3e50113dc4a0de19289b6354 upstream.

Commit a2468cc9bf ("swap: choose swap device according to numa node")
changed 'avail_lists' field of 'struct swap_info_struct' to an array.
In popular linux distros it increased size of swap_info_struct up to 40
Kbytes and now swap_info_struct allocation requires order-4 page.
Switch to kvzmalloc allows to avoid unexpected allocation failures.
