x86/entry/64: Add instruction suffix

Browse Source 
commit a368d7fd2a 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.
