drm/xe/client: bo->client does not need bos_lock
[ Upstream commit fc876c9524e2a9f816f51d533ed31df789cff65a ]
bos_lock is to protect list of bos used by client, it is
not required to protect bo->client so bring it outside of
bos_lock.
Fixes: b27970f3e11c ("drm/xe: Add tracking support for bos per client")
