iommufd: Improve a few unclear bits of code
Correct a few items noticed late in review:
- We should assert that the math in batch_clear_carry() doesn't underflow
- user->locked should be -1 not 0 sicne we just did mmput
- npages should not have been recalculated, it already has that value
No functional change.
Fixes: 8d160cd4d506 ("iommufd: Algorithms for PFN storage")
