Mike Gerdts 7241a075be bdev: hold spinlock while changing claim_module 
This closes races between concurrent spdk_bdev_module_claim_bdev()
and/or spdk_bdev_module_release_bdev() calls affecting the same bdev by
holding bdev->internal.spinlock while claiming and releasing a bdev. It
also closes a potential TOCTOU bug in that optimizing compilers probably
already eliminate in bdev_finish_unregister_bdevs_iter() and documents
that bdev->internal.claim_module is protected by
bdev->internal.spinlock.

This can be removed when the bdev_register_examine_thread deprecation
is removed.
