net: hns3: replace an unsuitable variable type in hclge_inform_reset_assert_to_vf()

Browse source

In hclge_inform_reset_assert_to_vf(), variable reset_type(enum type)
will be copied into msg_data whose size is 2 bytes. Currently, hip08
is a little-endian machine, so the lower two bytes of reset_type will
be copied to msg_data. But when running on a big-endian machine,
msg_data will have a wrong value(the higher two bytes of reset_type).

So this patch modifies the type of reset_type to u16, and adds a
build check in case enum hnae3_reset_type has value larger than
U16_MAX.
