SDAP: fix PDU session ID range validation logic

Browse Source 
Replace incorrect mathematical range check with explicit bounds
validation in nr_sdap_delete_entity(). The previous condition
(pdusession_id) * (pdusession_id - NR_MAX_NB_PDU_SESSIONS) > 0
was mathematically incorrect and could fail to properly validate
PDU session IDs.

PDU session ID validation now correctly rejects values outside
the valid range [0, NR_MAX_NB_PDU_SESSIONS]
