nvme: add context annotations for nvme_dev::shutdown_lock
nvme_setup_io_queues_trylock() conditionally acquires dev->shutdown_lock
using mutex_trylock(). The function returns 0 when the lock is
successfully acquired and a negative error code otherwise.
Annotate the function with __cond_acquires(0, &dev->shutdown_lock) so
that Clang's lock context analysis can track the lock state based on
the return value and verify correct lock usage at call sites.
