nvme: add context annotations for nvme_ctrl::ana_lock

Browse Source 
nvme_parse_ana_log() accesses ANA state protected by ctrl->ana_lock and
therefore requires callers to hold the lock.

Annotate nvme_parse_ana_log() with __must_hold(&ctrl->ana_lock) so that
Clang's lock context analysis can verify the locking requirement at
compile time.
