KVM: s390: vsie: fix < 8k check for the itdba
commit f4a551b72358facbbe5714248dff78404272feee upstream.
By missing an "L", we might detect some addresses to be <8k,
although they are not.
e.g. for itdba = 100001fff
!(gpa & ~0x1fffU) -> 1
!(gpa & ~0x1fffUL) -> 0
So we would report a SIE validity intercept although everything is fine.
Fixes: 166ecb3 ("KVM: s390: vsie: support transactional execution")
