Michal Luczaj 708f799d22 KVM: x86: Optimize kvm->lock and SRCU interaction (KVM_X86_SET_MSR_FILTER) ...

Reduce time spent holding kvm->lock: unlock mutex before calling
synchronize_srcu().  There is no need to hold kvm->lock until all vCPUs
have been kicked, KVM only needs to guarantee that all vCPUs will switch
to the new filter before exiting to userspace.
