mlxfw: fix null-ptr-deref in mlxfw_mfa2_tlv_next()
Function mlxfw_mfa2_tlv_multi_get() returns NULL if 'tlv' in
question does not pass checks in mlxfw_mfa2_tlv_payload_get(). This
behaviour may lead to NULL pointer dereference in 'multi->total_len'.
Fix this issue by testing mlxfw_mfa2_tlv_multi_get()'s return value
against NULL.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
