Subject: fabrics: avoid segfault if transport type is omitted
Git-commit: 565c8d2da873e143b343bdf42ea71e9aa9636efa
References: git-fixes

A nvme discover or connect-all would currently end up in a
segfault if the transport type is omitted as shown below:

nvme discover -w 192.168.1.114 -a 192.168.1.160
Segmentation fault (core dumped)

Avoid this segfault by checking if the transport type is
available before proceeding in get_default_trsvcid().
