hvm/vmx: WRITE_MSR() macro hygene

Use the standard "do { } while ( 0 )" semantics, and don't hide the break
statement, incase this macro wants to be used anywhere outside of a switch.

No functional change, but it is now clear that long_mode_do_msr_write()
doesn't have fallthough for the STAR, LSTAR and SYSCALL_MASK cases.
