[PATCH] net/ice: fix initialization with 8 ports

[PATCH] net/ice: fix initialization with 8 ports

[Bruce Richardson]

When initializing an 8-port device, the ACL configuration
failed with the adminq returning an ENOMEM status from the
sixth port onwards. Fix this issue by halving the depth, and
therefore the space required, when using a device with >4 PFs.
