KVM: x86: remove exit_int_info warning in svm_handle_exit

commit 05311ce954aebe75935d9ae7d38ac82b5b796e33 upstream.

It is valid to receive external interrupt and have broken IDT entry,
which will lead to #GP with exit_int_into that will contain the index of
the IDT entry (e.g any value).

Other exceptions can happen as well, like #NP or #SS
(if stack switch fails).

Thus this warning can be user triggred and has very little value.
