s390/cio: Fix incorrect xsch opcode specification
The numeric representation of the xsch instruction was incorrectly
specified, resulting in reserved fields of the instruction opcode
potentially being set to a non-zero value. While this doesn't currently
cause any problem, a future architecture might make use of these fields
so that the current specification could result in an exception or
unwanted side-effects.
Fix this by using the xsch instruction code for which support in
binutils was added in 2003.
