Subject: [PATCH 1/1] KVM: selftests: Fix force_emulation_prefix parameter type mismatch

Fix kvm_is_forced_enabled() to use get_kvm_param_bool() instead of
get_kvm_param_integer() when reading the "force_emulation_prefix" kernel
module parameter.

The force_emulation_prefix parameter is a boolean that accepts Y/N
values, but the function was incorrectly trying to parse it as an
integer using strtol().
