[PATCH 4/9] nvme-fabrics: remove dead hostnqn already-assigned check

[Guixin Liu]

The opts->host check in the NVMF_OPT_HOSTNQN handler can never fire:
options are parsed into a freshly allocated struct, and opts->host is
only assigned after the parsing loop completes. A duplicate hostnqn
option is already silently overridden by the strscpy() into the local
buffer. Remove the dead check.
