Jia He 9122bea986 hw/arm/smmuv3: Fix translate error handling
In case the STE's config is "Bypass" we currently don't set the
IOMMUTLBEntry perm flags and the access does not succeed. Also
if the config is 0b0xx (Aborted/Reserved), decode_ste and
smmuv3_decode_config currently returns -EINVAL and we don't enter
the expected code path: we record an event whereas we should not.

This patch fixes those bugs and simplifies the error handling.
decode_ste and smmuv3_decode_config now return 0 if aborted or
bypassed config was found. Only bad config info produces negative
error values. In smmuv3_translate we more clearly differentiate
errors, bypass/smmu disabled, aborted and success cases. Also
trace points are differentiated.

Fixes: 9bde7f0674 ("hw/arm/smmuv3: Implement translate callback")
