Subject: nvme: release namespace head reference on error
From: Keith Busch <kbusch@xxxxxxxxxx>
commit ac262508daa88fb12c5dc53cf30bde163f9f26c9 upstream.
If a namespace identification does not match the subsystem's head for
that NSID, release the reference that was taken when the matching head
was initially found.
