[PATCH 3/3] KVM: s390: memory leak in guest debug handling

[Christian Borntraeger <borntraeger@linux.ibm.com>]

bp_data is freed only for the error case by kfree(bp_data).
Every successful KVM_SET_GUEST_DEBUG will leak bp_data.

Fixes: 27291e2165b6 ("KVM: s390: hardware support for guest debugging")
