x86/asm/entry/64: Simplify retint_kernel label usage, make retint_restore_args label local
Get rid of #define obfuscation of retint_kernel in
CONFIG_PREEMPT case by defining retint_kernel label always, not
only for CONFIG_PREEMPT.
Strip retint_kernel of .global-ness (ENTRY macro) - it has no
users outside of this file.
This looks like cosmetics, but it is not:
"je LABEL" can be optimized to short jump by assember
only if LABEL is not global, for global labels jump is always
a near one with relocation.
Convert retint_restore_args to a local numeric label, making it
clearer that it is not used elsewhere in the file.
