net/ice: remove log from Tx prepare function

[ upstream commit 9aa546d868b60027a6723f1a772d287d44f17ef8 ]

ice_prep_pkts reports to the application that the packet is invalid
(from the driver pov). Having a log message in those branches is not
consistent with all other checks in this function and it may slow down
the application if such invalid packets are being sent continuously.

Fixes: ccf33dc ("net/ice: check illegal packet sizes")
Fixes: 688cb2f ("net/ice: fix scalar Tx path segment")
