target-z80: Fix handling of block in/out operations
This patch fixes BC register handling for block in/out operations; previous
code caused the value to underflow the 16bit range and eventually caused an
invalid memory access in the generic QEMU i/o code. The patch fixes also
Z, C and H flag behavior for block out operations. This further fixes Z
flag behavior for block in operations but still provides faulty behavior
for other flags.
