[ Upstream commit 615457a226f042bffc3a1532afb244cab37460d4 ]
Currently the for-loop counter i is a u8 however it is being checked
against a maximum value hw->num_tx_sched_layers which is a u16. Hence
there is a potential wrap-around of counter i back to zero if
hw->num_tx_sched_layers is greater than 255. Fix this by making i
a u16.
Addresses-Coverity: ("Infinite loop")
Fixes: b36c598c999c ("ice: Updates to Tx scheduler code")
