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.
