s390: get rid of superfluous __GFP_REPEAT

Browse Source 
__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations.

page_table_alloc then uses the flag for a single page allocation. This
means that this flag has never been actually useful here because it has
always been used only for PAGE_ALLOC_COSTLY requests.

An earlier attempt to remove the flag 10d58bf297 ("s390: get rid of
superfluous __GFP_REPEAT") has missed this one but the situation is very
same here.
