I renamed noop to nop, as that's the name of the instruction.

cheers

Print the function address associated with the restore_r2() error to
make it easier to debug the problem.

Also clarify the wording a bit.

Before:

  module_64: patch_foo: Expect noop after relocate, got 3c82

After:

  module_64: patch_foo: Expected noop after call, got 7c630034 at 
netdev_has_upper_dev+0x54/0xb0 [patch_foo]
