x86/entry/64: Add instruction suffix

commit a368d7fd2a3c6babb852fe974018dd97916bcd3b upstream.

Omitting suffixes from instructions in AT&T mode is bad practice when
operand size cannot be determined by the assembler from register
operands, and is likely going to be warned about by upstream gas in the
future (mine does already). Add the single missing suffix here.
