Daniel Henrique Barboza cd5d265f42 hw/riscv/riscv-iommu: change 'depth' to int 
Coverity reports an unsigned overflow when doing:

    for (; depth-- > 0; ) {

When depth = 0 inside riscv_iommu_ctx_fetch().

Building it with a recent GCC the code doesn't actually break with depth
= 0, i.e. the comparison "0-- > 0" will exit the loop instead of
proceeding,  but 'depth' will retain the overflow value afterwards.

This behavior can be compiler dependent, so change 'depth' to int to
remove this potential ambiguity.

Resolves: Coverity CID 1564783
Fixes: 0c54acb824 ("hw/riscv: add RISC-V IOMMU base emulation")
