iova: Remove magazine BUG_ON() checks

Browse source

Two of the magazine helpers have BUG_ON() checks, as follows:
- iova_magazine_pop() - here we ensure that the mag is not empty. However
  we already ensure that in the only caller, __iova_rcache_get().
- iova_magazine_push() - here we ensure that the mag is not full. However
  we already ensure that in the only caller, __iova_rcache_insert().

As described, the two bug checks are pointless so drop them.
