[PATCH] Double magic with '\&$x'

'\&$x' triggers double get magic when $x is just a scalar because of :
- the SvGETMAGIC in sv_2cv ;
- the SvPV_const in gv_fetchsv.
This patch moves the SvGETMAGIC into the two branches where gv_fetchsv
isn't called. This fixes the problem. Tested ok against 33623.

Actually, get magic also fires when it's not possible to create a sub of
name $x, because we call SvPV when building the croak message. This isn't
fixed by this patch. More generally, I'm wondering if magic actually has
to be triggered when assembling error messages.
