nvme: add context annotations for nvme_subsystems_lock
The global nvme_subsystems list, nvme_subsystem::entry,
nvme_subsystem::ctrls, and nvme_ctrl::subsys_entry are protected by
nvme_subsystems_lock. Annotate these objects with
__guarded_by(&nvme_subsystems_lock) so that Clang's context analysis
can validate accesses to them.
__nvme_find_get_subsystem() and nvme_validate_cntlid() traverse the
global subsystem list and subsystem controller list and therefore
require callers to hold nvme_subsystems_lock. Annotate both helpers
with __must_hold(&nvme_subsystems_lock).
