gv.c: Remove mro_method_changed_in() from gv_init

gv_init(_pvn) does not conceptually change anything.  There was
already a subroutine there before the stub was upgraded to a gv with
a real cv.

The example in the comment:

 sub Foo::bar($) { (shift) } sub ASDF::baz($); *ASDF::baz = \&Foo::bar

suggests that this was put in the wrong place to begin with.  Glob
assignment already takes care of mro_method_changed_in, so calling
it beforehand when reifying the glob is redundant.
