ice: Refactor getting/setting coalesce

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().
