[PATCH v4 14/20] nvme: add context annotations in fabric.c

[Nilay Shroff]

The global nvmf_transports list is protected by nvmf_transports_rwsem
and the global nvmf_hosts list is protected by nvmf_hosts_mutex.

Define both lists using LIST_HEAD_GUARDED() so that Clang's context
analysis can validate accesses to the lists against the corresponding
locking requirements.
