s390/cio/ioasm: Fix __xsch() condition code handling
commit f0edc8f113a39d1c9f8cf83e865c32b0668d80e0 upstream.
For the __xsch() inline assembly the conversion to flag output macros is
incomplete. Only the conditional shift of the return value was added, while
the required changes to the inline assembly itself are missing.
If compiled with GCC versions before 14.2 this leads to a double shift of
the cc output operand and therefore the returned value of __xsch() is
incorrectly always zero, instead of the expected condition code.
Fixes: e200565d434b ("s390/cio/ioasm: Convert to use flag output macros")
