Create an rcu_dereference_check_fdtable() that encapsulates the
rcu_dereference_check() condition for fcheck_files() use. This
has the beneficial side-effect of getting rid of a very long
line.

Impact: cleanup
We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace
changes), but this is not possible currently without breaking the
build because fdtable.h has an implicit include file dependency: it
uses __init does not include init.h.
This can cause build failures on non-x86 architectures:
/home/mingo/tip/include/linux/fdtable.h:66: error: expected '=', ',',
';', 'asm' or '__attribute__' before 'files_defer_init'
make[2]: *** [fs/locks.o] Error 1
We got this header included indirectly via rcupdate.h's percpu.h
inclusion - but if that is not there the build will break.
Fix it.

Instead of creating the "filp" kmem_cache in vfs_caches_init(),
we can do it a litle be later in files_init(), so that filp_cachep
is static to fs/file_table.c
