watchdog: diag288_wdt: fix __diag288() inline assembly
commit 32e40f9506b9e32917eb73154f93037b443124d1 upstream.
The DIAG 288 statement consumes an EBCDIC string the address of which is
passed in a register. Use a "memory" clobber to tell the compiler that
memory is accessed within the inline assembly.
