[PATCH 04/14] KVM: monolithic: x86: handle the request_immediate_exit variation

[Andrea Arcangeli]

request_immediate_exit is one of those few cases where the pointer to
function of the method isn't fixed at build time and it requires
special handling because hardware_setup() may override it at runtime.
