block/bio: Remove null checks before mempool_destroy in bioset_free

This patch removes redundant checks for null values on bio_pool and bvec_pool.

Found using make coccicheck M=block/ on linux-net tree on the next-20170929 tag.

Related to patch 9987695 that removed similar checks in bio-integrity.

Applied, but ditto on the line length. Additionally, I killed that reference to "patch 9987695", I don't know what that means? What does that refer to?

The patch number I referenced is what is used on patchwork.com to reference a patch under review. I'll leave that out in the next message. What is the proper manner of referencing another patch thats still in review?
