Improve debug assertion for runtime svc number

Browse source 
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.
