KVM: nVMX: Replace a BUG_ON(1) with BUG() to squash clang warning
Use BUG() in the impossible-to-hit default case when switching on the
scope of INVEPT to squash a warning with clang 11 due to clang treating
the BUG_ON() as conditional.
>> arch/x86/kvm/vmx/nested.c:5246:3: warning: variable 'roots_to_free'
is used uninitialized whenever 'if' condition is false
[-Wsometimes-uninitialized]
BUG_ON(1);
Reported-by: kbuild test robot <lkp@intel.com>
Fixes: ce8fe7b77bd8 ("KVM: nVMX: Free only the affected contexts when emulating INVEPT")
