[PULL 81/92] helper_syscall x86_64: clear exception_is_int

[Paolo Bonzini]

From: Douglas Crosher <dtc-ubuntu@scieneer.com>

The exception_is_int flag may be set on entry to helper_syscall,
e.g. after a prior interrupt that has returned, and processing
EXCP_SYSCALL as an interrupt causes it to fail so clear this flag.
