ibmvnic: handle inconsistent login with reset

[ Upstream commit 31d6b4036098f6b59bcfa20375626b500c7d7417 ]

Inconsistent login with the vnicserver is causing the device to be
removed. This does not give the device a chance to recover from error
state. This patch schedules a FATAL reset instead to bring the adapter
up.
