vfs: __read_cache_page should use gfp argument rather than GFP_KERNEL

commit e6f67b8c05f5e129e126f4409ddac6f25f58ffcb upstream.

lockdep reports a deadlock in jfs because a special inode's rw semaphore
is taken recursively.  The mapping's gfp mask is GFP_NOFS, but is not
used when __read_cache_page() calls add_to_page_cache_lru().
