avoid endless loops in lib/swiotlb.c
Commit 681cc5cd3efbeafca6386114070e0bfb5012e249 ("iommu sg merging:
swiotlb: respect the segment boundary limits") introduced two
possibilities for entering an endless loop in lib/swiotlb.c:
- if max_slots is zero (possible if mask is ~0UL)
- if the number of slots requested fits into a swiotlb segment, but is
too large for the part of a segment which remains after considering
offset_slots
This fixes them
