KVM: selftests: fix vmx_preemption_timer_test build with GCC10

Browse Source 
GCC10 fails to build vmx_preemption_timer_test:

gcc -Wall -Wstrict-prototypes -Wuninitialized -O2 -g -std=gnu99

ctrl_exit_rev/ctrl_pin_rev/basic variables are only used in
vmx_preemption_timer_test.c, just move them there.
