target/hppa: Fix DCOR reconstruction of carry bits
The carry bits for each nibble N are located in bit (N+1)*4,
so the shift by 3 was off by one. Furthermore, the carry bit
for the most significant carry bit is indeed located in bit 64,
which is located in a different storage word.
Use a double-word shift-right to reassemble into a single word
and place them all at bit 0 of their respective nibbles.
