s390: fix compile error with memmove_early() inline assembly
Old gcc versions can't handle a bogus early clobber on a Q constraint:
arch/s390/kernel/early.c: In function 'memmove_early.part.1':
arch/s390/kernel/early.c:432:2: error: '&' constraint used with no register class
Simply remove it to fix this.
