powerpc/modules: Improve restore_r2() error message
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 3c820000
After:
module_64: patch_foo: Expected nop after call, got 7c630034 at netdev_has_upper_dev+0x54/0xb0 [patch_foo]
