nvme: add context annotations for nvme_passthru_{start|stop}

Annotate nvme_passthru_start() and nvme_passthru_end() for Clang
context/thread-safety analysis.

The __cond_acquires() and __cond_releases() annotations model
conditional lock acquisition and release based on a function's return
value. Use a nonzero return value as the abstract condition denoting
that the associated locks have been acquired or released.

This allows the analyzer to track the lock state across the
nvme_passthru_start() / nvme_passthru_end() pair and verify correct
locking semantics.
