Dmitry Bogdanov 431e58d56f nvmet: fix memory leak of bio integrity ...

[ Upstream commit 190f4c2c86 ]

If nvmet receives commands with metadata there is a continuous memory
leak of kmalloc-128 slab or more precisely bio->bi_integrity.

Since commit bf4c89fc87 ("block: don't call bio_uninit from bio_endio")
each user of bio_init has to use bio_uninit as well. Otherwise the bio
integrity is not getting free. Nvmet uses bio_init for inline bios.

Uninit the inline bio to complete deallocation of integrity in bio.

Fixes: bf4c89fc87 ("block: don't call bio_uninit from bio_endio")
