hw_x86_64: Perform the user entry mode transition 

The interrupt return instruction in IA-32e mode applies the prepared
interrupt stack frame to set the RFLAGS, CS and SS segment as well as
the RIP and RSP registers. It then continues execution of the user code.

For detailed information refer to Intel SDM Vol. 3A, section 6.14.3.
