Improve __fget_files_rcu() code generation (and thus __fget_light())
Commit 0ede61d8589c ("file: convert to SLAB_TYPESAFE_BY_RCU") caused a
performance regression as reported by the kernel test robot.
The __fget_light() function is one of those critical ones for some
loads, and the code generation was unnecessarily impacted. Let's just
write that function to better.
