dwarf2loc.c: minor cleanup. don't print integer with paddress.

dwarf2loc.c: minor cleanup. don't print integer with paddress.

A couple years ago, dwarf_expr_fetch used to return a CORE_ADDR.  It
was made to return a ULONGEST since, and the 'dwarf_regnum' local
adjusted accordingly, but, we kept printing it with paddress.
gdbarch_dwarf2_reg_to_regnum takes the register number as 'int', so
there's really no point in using ULONGEST/pulongest either.

	* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): 'dwarf_regnum'
	local is now int instead of ULONGEST.  Print it with %d
	instead of paddress.
