Maciej Fijalkowski f9124c68f0 ice: synchronize_rcu() when terminating rings
Unfortunately, the ice driver doesn't respect the RCU critical section that
XSK wakeup is surrounded with. To fix this, add synchronize_rcu() calls to
paths that destroy resources that might be in use.

This was addressed in other AF_XDP ZC enabled drivers, for reference see
for example commit b3873a5be7 ("net/i40e: Fix concurrency issues
between config flow and XSK")

Fixes: efc2214b60 ("ice: Add support for XDP")
Fixes: 2d4238f556 ("ice: Add support for AF_XDP")
