net: ieee802154: remove an unnecessary null pointer check
llsec_parse_seclevel has the null pointer check at its begining. Compared
with nl802154_add_llsec_seclevel, nl802154_del_llsec_seclevel has a
redundant null pointer check of info->attrs[NL802154_ATTR_SEC_LEVEL]
before llsec_parse_seclevel.
Fix this issue by removing the null pointer check in
nl802154_del_llsec_seclevel.
