ANDROID: mm: Use intended order-adjusted batch size

Browse Source 
Commit 44042b4498 ("mm/page_alloc: allow high-order pages to be stored
on the per-cpu lists") adjusts the pcp batch size __rmqueue_pcplist()
allocates from rmqueue_bulk() in proportion to the page order.

This line was not properly carried forward when porting
commit 37b2d597bb ("ANDROID: mm: add cma pcp list") to android 13-5.15.
