Drop nested_vmx_l1_wants_exit()'s initialization of intr_info from
vmx_get_intr_info() that was inadvertantly introduced along with the
caching mechanism.  EXIT_REASON_EXCEPTION_NMI, the only consumer of
intr_info, populates the variable before using it.

Fixes: bb53120d67cdb ("KVM: VMX: Cache vmcs.EXIT_INTR_INFO using arch avail_reg flags")
