Peter Zijlstra 18acb7fac2 bpf: Revert ("Fix dispatcher patchable function entry to 5 bytes nop") 
Because __attribute__((patchable_function_entry)) is only available
since GCC-8 this solution fails to build on the minimum required GCC
version.

Undo these changes so we might try again -- without cluttering up the
patches with too many changes.

This is an almost complete revert of:

  dbe69b2998 ("bpf: Fix dispatcher patchable function entry to 5 bytes nop")
  ceea991a01 ("bpf: Move bpf_dispatcher function out of ftrace locations")

(notably the arch/x86/Kconfig hunk is kept).
