One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)

Notice that, in this case, variable size is not necessary, hence it
is removed.

Currently if the driver has an uneven amount of Rx/Tx queues
setting the coalesce settings through ethtool will result in
an error. This is happening because in the setting coalesce
flow we are reporting an error if either Rx or Tx fails.

Also, the flow for setting/getting per_q_coalesce and
setting/getting coalesce settings for the entire device
is different.

Fix these issues by adding one function, ice_set_q_coalesce(),
and another, ice_get_q_coalesce(), that both getting/setting
per_q and entire device coalesce can use. This makes handling
the error cases generic between the two flows and simplifies
__ice_set_coalesce() and __ice_get_coalesce().

Also, add a header comment to __ice_set_coalesce().

and unnecessary to have a difference between the two flows.
