xdp: Remove WARN() from __xdp_reg_mem_model()

CWE ID: N/A

Base Score (CVSS): N/A

CVE: CVE-2024-42082

Descrizione: xdp: The vulnerability has been resolved. The following issue has been addressed: – Remove WARN() from __xdp_reg_mem_model(). – A warning is reported in __xdp_reg_mem_model(). – The warning occurs only when __mem_id_init_hash_table() returns an error. – This error occurs in two cases: 1. Memory allocation fails. 2. rhashtable_init() fails when some fields of rhashtable_params struct are not properly initialized. – Therefore, the WARN() function is safely removed.
