[PATCH V2 0/2] nvme: fix module ref count Oops

[Chaitanya Kulkarni]

Hi,

For nvme-ctrl char device we don't currently get the ctrl's module
refcount. This leads to the Oops. In this series, we get/put the 
module refcount in nvme-ctrl char dev open/release, lift the file
opening from the host-core to caller in the NVMeOF target
passthru and take the ctrl refcount in into the 
nvmet_passthru_ctrl_enable().

Changes from V1: -

1. Move last patch to get the module refcount to start of the series.
2. De-couple the module refcount get/put from nvme_dev_open() and
   nvme_dev_release().
