Nick Piggin 0ae0b5d055 fs/splice.c: fix mapping_gfp_mask usage ...

mapping_gfp_mask() is not supposed to store allocation contex details,
only page location details.  So mapping_gfp_mask should be applied to the
pagecache page allocation, wheras normal (kernel mapped) memory should be
used for surrounding allocations such as radix-tree nodes allocated by
add_to_page_cache.  Context modifiers should be applied on a per-callsite
basis.

So change splice to follow this convention (which is followed in similar
code patterns in core code).
