x86/entry/64: Add instruction suffix to SYSRET
ignore_sysret() contains an unsuffixed SYSRET instruction. gas correctly interprets this as SYSRETL, but leaving it up to gas to guess when there is no register operand that implies a size is bad practice, and upstream gas is likely to warn about this in the future. Use SYSRETL explicitly. This does not change the assembled output.
