Description
There are two issues in nvme_dskname(). First, it is assumed that the output of di_dim_path_dev() either returns NULL or a string that is at least 2 chars long. And second, there is an ineffective NULL pointer check following strrchr(path, '/') + 1.

Testing: I verified that the disk names are still resolved correctly by nvmeadm, but I didn't exercise the error handling for when di_dim_path_dev() does something completely unexpected.
This change has been in illumos-joyent since July.
