Davide Caratti aa81700cf2 macsec: fix NULL dereference in macsec_upd_offload()
macsec_upd_offload() gets the value of MACSEC_OFFLOAD_ATTR_TYPE
without checking its presence in the request message, and this causes
a NULL dereference. Fix it rejecting any configuration that does not
include this attribute.
