e2e: restrict IO with lower version kernel at rbd-nbd tests
Currently, at "perform IO on rbd-nbd volume after nodeplugin restart" test we are performing write on the rbd-nbd based mount after nodeplugin restart. But due to a bug in NBD driver the writes are failing, please note NBD zero cmd timeout handling is fixed with kernel >= 5.4 and hence we should defend on writes based on kernel version to avoid unnecessary CI failures. For more information see https://github.com/ceph/ceph-csi/issues/2204#issuecomment-930941047 updates: #2204 Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
