i40e: Fix filter input checks to prevent config with invalid values

[ Upstream commit 3e48041d9820c17e0a51599d12e66c6e12a8d08d ]

Prevent VF from configuring filters with unsupported actions or use
REDIRECT action with invalid tc number. Current checks could cause
out of bounds access on PF side.

Fixes: e284fc280473 ("i40e: Add and delete cloud filter")
