[PATCH 5.10 117/717] ionic: change set_rx_mode from_ndo to can_sleep

Greg Kroah-Hartman

From: Shannon Nelson <snelson@pensando.io>

[ Upstream commit 81dbc24147f9250c186ae5875b3ed3136e9e293b ]

Instead of having two different ways of expressing the same
sleepability concept, using opposite logic, we can rework the
from_ndo to can_sleep for a more consistent usage.

Fixes: 1800eee16676 ("net: ionic: Replace in_interrupt() usage.")
