RFA: use init_type() in dwarf2read.c

[Fred Fish <fnf@fishpond.ninemoons.com>]

The dwarf2read.c file sometimes handcrafts new types and sometimes
calls init_type().  This patch eliminates one of the unnecessary
handcraftings.

	* dwarf2read.c (read_typedef):  Replace hand crafted type
	initialization with a call to the init_type() function, which
	is how the rest of gdb creates types.
