[PATCH] nvme/mpath: fix hang when disk goes live over reconnect

[Anton Eidelman]

The wrapper is to:
- follow the naming convention for mpath functions called from core
- allow the implementation to have more logic in future

As for error propagation, nvme_start_ctrl is void.
Any error in nvme_read_ana_log() will have the same effect as
when it is invoked from nvme_ana_work(), i.e. will be ignored.
