[PATCH] nvme-core: don't initlialize ctrl->cntlid twice

[andrew.smirnov@gmail.com (Andrey Smirnov)]

ctrl->cntlid will already be initialized from id->cntlid for
non-NVME_F_FABRICS controllers few lines below. For NVME_F_FABRICS
controllers this field should already be initialized, otherwise the
check

	if (ctrl->cntlid != le16_to_cpu(id->cntlid))

below will always be a no-op.

I created this patch just from readying NVMe code. Appologies for the
noise if I misread/misinterpreted things and this assignment is
actually necessary.

Thanks,
Andrey Smirnov
