x86-64: Always display suffix for %LQ in 64bit

x86-64: Always display suffix for %LQ in 64bit

In 64bit, assembler generates a warning for "sysret":

$ echo sysret | as --64 -o x.o -
{standard input}: Assembler messages:
{standard input}:1: Warning: no instruction mnemonic suffix given and no register operands; using default for `sysret'

Always display suffix for %LQ in 64bit to display "sysretl".
