Subject: ionic: clear linkcheck bit on alloc fail
Patch-mainline: v5.10-rc1
Git-commit: 2c580d7783c78c115cea9e50b43477f3eab5076d
References: jsc#SLE-16649

Clear our link check requested flag on an allocation error.
We end up dropping this link check request, but that should
be fine as our watchdog will come back a few seconds later
and request it again.
