Gustavo A. R. Silva d52c499b47 lightnvm: pblk: fix use-after-free bug 
Remove one of the calls to function bio_put(), so *bio* is only
freed once.

Notice that bio is being dereferenced in bio_put(), hence leading to
a use-after-free bug once *bio* has already been freed.

Addresses-Coverity-ID: 1475952 ("Use after free")
Fixes: 55d8ec3539 ("lightnvm: pblk: support packed metadata")
