Subject: ice: remove redundant variable and if condition
Patch-mainline: v5.2-rc1
Git-commit: 16c3301b55668fe8b163cad5c6b4d064bfa7c6fc
References: jsc#SLE-4803
In ice_pf_rxq_wait we are using an unnecessary local variable and also
we are checking if the timeout time was reached after the loop. Get rid
of the local variable and return 0 right when we get a successful
result. This makes it so we can return -ETIMEDOUT if we ever exit the
loop because we know the timeout time has been hit.
