x86_64/locore.S: Fix SWAPGS state clobbered in ast_from_interrupt
When ast_from_interrupt fires on a user-mode interrupt,
POP_AREGS_ISR restores the user's r12, clobbering the SWAPGS state
that was set by SWAPGS_ENTRY_IF_NEEDED_R12 on interrupt entry.
Since the user's r12 value is preserved on the stack by pusha,
we set the state back to RETURN_TO_USER before calling _return_from_trap.
