PATCH: use frame_unwind_register instead of frame_register

Committed as obvious --- frame_unwind_register takes care of passing
all the dummy arguments to frame_register, so dwarf_expr_read_reg
shouldn't have to bother.

* dwarf2loc.c (dwarf_expr_read_reg): Use frame_unwind_register
instead of frame_register. Doc fix.
