[net-next 04/15] i40evf: remove unnecessary log messages

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Mitch Williams <mitch.a.williams@intel.com>

We don't need to print log messages when we encounter an out-of-memory
condition, as the allocator will do this for us. Also, remove a Tx hang
message that duplicates the one emitted by the netdev layer, and a
duplicate message in the watchdog.
