Daniel Morsing 7cfa8310c7 cmd/gc: fix issue with method wrappers not having escape analysis run on them.
Escape analysis needs the right curfn value on a dclfunc node, otherwise it will not analyze the function.
When generating method value wrappers, we forgot to set the curfn correctly.

Fixes #5753.
