mm/filemap.c: fix an overly long line in read_cache_page

Patch series "fix filler_t callback type mismatches", v2.

Casting mapping->a_ops->readpage to filler_t causes an indirect call
type mismatch with Control-Flow Integrity checking.  This change fixes
the mismatch in read_cache_page_gfp and read_mapping_page by adding
using a NULL filler argument as an indication to call ->readpage
directly, and by passing the right parameter callbacks in nfs and jffs2.

This patch (of 4):

Code cleanup.
