Improve debug assertion for runtime svc number
This patch improves the debug assertion for runtime svc number
- Remove useless comparison ensuring that the number of descriptors
is a positive number. The variable is an unsigned integer so can't
be negative.
- Check that the end address of the descriptors is sane relative
to the start address.
