Richard Henderson 709fe27b18 semihosting: Adjust error checking in common_semi_cb ...

The err parameter is non-zero if and only if an error occured.
Use this instead of ret == -1 for determining if we need to
update the saved errno.

This fixes the errno setting of SYS_ISTTY, which returns 0 on
error, not -1.
