wifi: iwlwifi: mvm: use IWL_FW_CHECK for link ID check

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2085849

[ Upstream commit 9215152677d4b321801a92b06f6d5248b2b4465f ]

The lookup function iwl_mvm_rcu_fw_link_id_to_link_conf() is
normally called with input from the firmware, so it should use
IWL_FW_CHECK() instead of WARN_ON().
