[PATCHv2 blktests 1/2] nvme/052: move nvmf_wait_for_ns() to common/nvme

[Nilay Shroff]

In a preparation for the use of nvmf_wait_for_ns function from
other nvme test script, move nvmf_wait_for_ns from nvme/052 to
common/nvme file so that we can reuse the nvmf_wait_for_ns from
multiple test scripts.
